* Disable Dx12 half tests. The half-calc test runs, but is not actually doing any half maths. If the code is changed such that it is, the device fails when the shader is used. This can be seen by looking at dxil-asm.

* Improve support for interfaces as shader parameters
This change adds two main things over the existing support:
1. It is now possible to plug in concrete types that actually contain (uniform/ordinary) fields for the existential type parameters introduced by interface-type shader parameters. The `interface-shader-param2.slang` test shows that this works.
2. There is a limited amount of support for doing correct layout computation and generating output code that matches that layout, so that interface and ordinary-type fields can be interleaved to a limited extent. The `interface-shader-param3.slang` test confirms this behavior.
There are several moving pieces in the change.
* When it comes to terminology, we try to draw a more clear distinction between existial type parameters/arguments and existential/object value parametes/arguments. A simple way to look at it is that an `IFoo[3]` shader parameter introduces a single existential type parameter (so that a concrete type argument like `SomeThing` can be plugged in for the `IFoo`) but introduces three existential object/value parameters (to represent the concrete values for the array elements).
* At the IR level, we support a few new operations. A `BindExistentialsType` can take a type that is not itself an interface/existential type but which depends on interfaces/existentials (e.g., `ConstantBuffer<IFoo>`) and plug in the concrete types to be used for its existential type slots.
* Then a `wrapExistentials` instruction can take a type with all the existentials plugged in (possibly by `BindExistentialsType`) and wrap it into a value of the existential-using type (e.g., turn `ConstantBuffer<SomeThing>` into a `ConstantBuffer<IFoo>`).
* The IR passes for doing generic/existential specialization have been updated to be able to desugar uses of these new operations just enough so that a `ConstantBuffer<IFoo>` can be used.
* When we specialize an IR parameter of an interface type like `IFoo` based on a concrete type `SomeThing`, we turn the parameter into an `ExistentialBox<SomeThing>` to reflect the fact that we are conceptually referring to `SomeThing` indirectly (it shouldn't be factored into the layout of its surrounding type).
* Parameter binding was updated so that it passes along the bound existential type arguments in a `Program` or `EntryPoint` to type layout, so that we can take them into account. The type layout code needs to do a little work to pass the appropriate range of arguments along to sub-fields when computing layout for aggregate types.
* Type layout was updated to have a notion of "pending" items, which represent the concrete types of data that are logically being referenced by existential value slots. The basic idea is that these values aren't included in the layout of a type by default, but then they get "flushed" to come after all the non-existential-related data in a constant buffer, parameter block, etc.
* The logic for computing a parameter group (`ConstantBuffer` or `ParameterBlock`) layout was updated to always "flush" the pending items on the element type of the group, so that the resource usage of specialized existential slots would be taken into account.
* The type legalization pass has been adapted so that we can derive two different passes from it. One does resource-type legalization (which is all that the original pass did). The new pass uses the same basic machinery to legalize `ExistentialBox<T>` types by moving them out of their containing type(s), and then turning them into ordinary variables/parameters of type `T`.
Big things missing from this change include:
- Nothing is making sure that "pending" items at the global or entry-point level will get proper registers/bindings allocated to them. For the uniform case, all that matters in the current compiler is that we declare them in the right order in the output HLSL/GLSL, but for resources to be supported we will need to compute this layout information and start associating it with the existential/interface-type fields.
- Nothing is being done to support `BindExistentials<S, ...>` where `S` is a `struct` type that might have existential-type fields (or nested fields...). Eventually we need to desugar a type like this into a fresh `struct` type that has the same field keys as `S`, but with fields replaced by suitable `BindExistentials` as needed. (The hard part of this would seem to be computing which slots go to which fields). As a practial matter, this missing feature means that interface-type members of `cbuffer` declarations won't work.
The current tests carefully avoid both of these problems. They don't declare any buffer/texture fields in the concrete types, and they don't make use of `cbuffer` declarations or `ConstantBuffer`s over structure types with interface-type fields.

* Fix up handling of NumElements for D3D buffer views
For everything but structured buffers we'd been setting this to the size in bytes, but that isn't really valid at all.
The `NumElements` member in the view descs is supposed to be the number of buffer elements, so it would be capped at the byte size divided by the element size.
This change fixes the computation of `NumElements` to take the size of the format into account for non-structured views.
For the "raw" case, we use a size of 4 bytes since that matches the `DXGI_FORMAT_R32_TYPELESS` format we use (which seems to be required for raw buffers).
I also added support for the raw case for SRVs where it didn't seem to be supported before (not that any of our tests cover it).
* Fix handling of size padding for D3D11 buffers
The existing code was enforcing a 256-byte-aligned size for all buffers, but this can cause problems for a structured buffer.
A structured buffer must have a size that is a multiple of the stride, so a structured buffer with a 48-byte stride and a 96-byte size would get rounded up to 256 bytes, which is not an integer multiple of 48.
This change makes it so that we only apply the padding to constant buffers.
According to MSDN, constant buffers only require padding to a 16-byte aligned size, and no other restrictions are listed for D3D11, but it is difficult to know whether those constrains are exhaustive.
I've left in the 256-byte padding for now (rather than switch to 16-byte), even though I suspect that was only needed as a band-aid for the `NumElements` issue fixed by another commit.
* Fix an IR generation bug when indxing into a strutured buffer element
The problem here arises when we have a structured buffer of matrices (an array type would likely trigger it too):
```hlsl
RWStructuredBuffer<float3x4> gMatrices;
```
and then we index into it directly, rather than copying to a temporary:
```hlsl
// CRASH:
float v = gMatrices[i][j][k];
// OKAY:
float3x4 m = gMatrices[i];
float v = m[j][k];
```
The underlying issue is that our IR lowering pass tries to defer the decision about whether to use a `get` vs. `set` vs. `ref` accessor for a subscript until as late as possible (this is to deal with the fact that sometimes D3D can provide a `ref` accessor where GLSL can only provide a `get` or `set`).
We probably need to overhaul that aspect of IR codegen sooner or later, but this change uses some of the existing machinery to try to force the `gMatrices[i]` subexpression to take the form of a pointer when doing sub-indexing like this. This fixes the present case, and hopefully shouldn't break anything else that used to work (because the subroutines I'm using to coerce the `gMatrices[i]` expression should be idempotent on the cases that were already implemented).
* Add a test case to confirm fxc/dxc layout for structured buffers of matrices
Even when row-major layout is requested globally, fxc and dxc seem to lay out a `StructuredBuffer<float3x4>` with column-major layout on the elements.
This commit adds a test that confirms that behavior.
This commit does not try to implement a fix for the issue (either fixing Slang's layout reflection information to be correct for what fxc/dxc do in practice, or fixing Slang's HLSL output to work around the fxc/dxc behavior), but just documents the status quo.
If/when we decide how we'd like to handle the issue long-term, this test can/should be updated to match the decision we make.
* fixup: build breakage on clang/gcc
This is one of those cases where the Microsoft compiler is letting through some stuff that isn't technically valid C++ ("delayed template parsing").
Fixed by just moving some declarations to earlier in the file.

Fixes issue #874
The problem here was that a pointer was being cast to `LONG` so that it could be used with the `SetWindowLongPtr` API, but that API actually expects a `LONG_PTR`. Since `LONG` is a 32-bit type on 64-bit Windows, the pointer we stored was getting truncated, leading to crashes.
I'm kind of surprised this wasn't biting more of our applications (e.g., the render tests).

* First steps toward supporting interface-type parameters on shaders
What's New
----------
From the perspective of a user, the main thing this change adds is the ability to declare top-level shader parameters (either at global scope, or in an entry-point parameter list) with interface types. For example, the following becomes possible:
```hlsl
// Define an interface to modify values
interface IModifier { float4 modify(float4 val); }
// Define some concrete implementations
struct Doubler : IModifier
{
float4 modify(float4 val) { return val + val; }
}
struct Squarer : IModifier { ... }
// Define a global shader parameter of interface type
IModifier gGlobalModifier;
// Define an entry point with an interface-type `uniform` parameter
void myShader(
unifrom IModifier entryPointModifier,
float4 inColor : COLOR,
out float4 outColor : SV_Target)
{
// Use the interface-type parameters to compute things
float4 color = inColor;
color = gGlobalModifier.modify(color);
color = entryPointModifier.modify(color);
outColor = color;
}
```
The user can specialize that shader by specifying the concrete types to use for global and entry-point parameters of interface types (e.g., plugging in `Doubler` for `gGlobalModifier` and `Squarer` for `entryPointModifier`).
The "plugging in" process is done in terms of a concept of both global and local "existential slots" which are a new `LayoutResourceKind` that represents the holes where concrete types need to be plugged in for existential/interface types.
In simple cases like the above, each interface-type parameter will yield a single existential slot in either the global or entry-point parameter layout. Users can query the start slot and number of slots for each shader parameter, just like they would for any other resource that a parameter can consume. Before generating specialized code, the user plugs in the name of the concrete type they would like to use for each slot using `spSetTypeNameForGlobalExistentialSlot` and/or `spSetTypeNameForEntryPointExistentialSlot`.
There are some major limitations to the implementation in this first change:
* Parameters must be of interface type (e.g., `IFoo`) and not an array (`IFoo[3]`), or buffer (`ConstantBuffer<IFoo>`) over an interface type. Similarly, `struct` types with interface-type fields still don't work.
* The work on interface-type function parameters still doesn't include support for `out` or `inout` parameters, nor for functions that return interface types (that isn't technically related to this change, but affects its usefullness).
* No work is being done to correctly lay out shader parameters once the concrete types for existential slots are known, so that this change really only works when the concrete type that gets plugged in is empty.
These limitations are severe enough that this feature isn't really usable as implemented in this change, and this merely represents a stepping stone toward a more complete implementation.
Implementation
--------------
The API side of thing largely mirrors what was already done to support passing strings for the type names to use for global/entry-point generic arguments, so there should be no major surprises there.
The logic in `check.cpp` computes the list of existential slots when creating unspecialized `Program`s and `EntryPoint`s (this is logically the "front end" of the compiler), and then checks the supplied argument types against what is expected in each slot when creating specialized `Program`s and `EntryPoint`s. This again mirrors how generic arguments are handled.
Type layout was extended to compute the number of existential slots that a type consumes, and will thus automatically assign ranges of slots to top-level and entry-point shader parameters in the same way it already allocates `register`s and `binding`s. The big missing feature is the ability to specialize a layout to account for the concrete types plugged into the existential-type slots.
IR generation for specialized programs and entry points was slightly extended so that it attaches information about the concrete types plugged into the existential slots, and the witness tables that show how they conform to the interface for that slot. The linking step needed some small tweaks to make sure that information gets copied over to the target-specific program when we start code generation.
The meat of the IR-level work is in `ir-bind-existentials.cpp`, which takes the information that was placed in the IR module by the generation/linking steps and uses it to rewrite shader parameters. For example, if there is a shader parameter `p` of type `IModifier`, and the corresponding existential slot has the type `Doubler` in it, we will rewrite the parameter to have type `Doubler`, and rewrite any uses of `p` to instead use `makeExistential(p, /*witness that Doubler conforms to IModifier*/)`.
Once the replacement is done on the parameters, the existing work for specializing existential-based code when the input type(s) are known kicks in and does the rest.
Testing
-------
A single compute test is added to validate that this feature works. It is narrowly tailored to not require any of the features not supported by the initial implementation (e.g., all of the concrete types used have no members).
The test case *does* include use of an associated type through one of these existential-type parameters, which has exposed a subtle bug in how "opening" of existential values is implemented in the front-end. Rather than fix the underlying problem, I cleaned up the code in the front-end to special case when the existential value being opened is a variable bound with `let`, to directly use a reference to that variable rather than introduce a temporary. Similarly, in the IR generation step, I added an optimization to make variables declared with `let` skip introducing an IR-level variable and just use the SSA value of their initializer directly instead.
* fixup: missing files
* fixup: incorrect type for unreachable return
* fixup: actually comment ir-bind-existentials.cpp

* Split front- and back-ends
This change is a major refactor of several of the types that provide the behind-the-scenes implementation of the public C API.
The goal of this refactor is primarily to allow for future API services that let the user operate both the front- and back-ends of the compiler in a more complex fashion.
For example, as user should be able to compile a bunch of source code into modules, look up types, functions, etc. in those modules, specialize generic types/functions to the types they've looked up, and then finally request target code to be gernerated for specialized entry points.
The back-end code generation they trigger should re-use the front-end compilation work (parsing, semantic checking, IR generation) that was already performed.
The most visible change is that `CompileRequest` has been split up into several smaller types that take responsibility for parts of what it did:
* The `Linkage` type owns the storage for `import`ed modules, and well as the `TargetRequest`s that represent code-generation targets. The intention is that an application could use a single `Linkage` for the duration of its runtime (so long as it was okay with the memory usage), so that each `import`ed module only gets loaded once. For now, this type needs to manage the search paths, file system, and source manager, because of its responsibility for loading files.
* A `FrontEndCompileRequest` owns the stuff related to parsing, semantic checking, and initial IR generation. This most notably includes the `TranslationUnitRequest`s and the `FrontEndEntryPointRequest`s (which used to be just `EntryPointRequest`s). It's main job is to produce AST and IR modules for each translation unit, and to find and validate the entry points. The front-end request does *not* interact with generic arguments for global or entry-point generic parameters.
* The main output of both `import` operations and front-end translation units is the `Module` type, which is just a simple container for both the AST module (to service the reflection/layout APIs, and also for semantic checking of code that `import`s the module) and the IR module (for linking and code generation). This type captures the commonalities between the old `LoadedModule` (which is now just an alias for `Module`) and `TranslationUnitRequest` (which now owns a `Module`).
* The secondary output of front-end compilation is a `Program`, which comprises a list of referenced `Module`s and validated `EntryPoint`s that will be used together. Layout and code generation both need a `Program` to tell them what modules and entry points will be used together (we don't want to just code-gen everythin that has ever been loaded into the linakge). The `Program`s created by the front-end do not include generic arguments, so they may provide incomplete layout information and/or be unsuitable for code generation.
* A `BackEndCompileRequest` owns stuff related to turning a `Program` into output kernels for the targets of a `Linkage`. Most of the data it owns beyond the `Program` to be compiled is minor, so this is a good candidate for demotion from a heap-allocated object to just a `struct` of options that gets passed around.
* The `CompileRequestBase` type is an attempt to wrap up the common functionality of both front-end and back-end compile requests. Most of it is just exposing the availability of a linkage and `DiagnosticSink`, so this type is a good candidate for subsequent removal. The main interesting thing it has is the flags related to dumping and validation of IR, so there is probably a good refactoring still to be made around deciding how options should be handled going forward.
* Behind the scenes, the `Program` type is set up to handle some level of on-line compilation and layout work. The `Program` knows the `Linkage` it belongs to, and allows for a `TargetProgram` to be looked up based on a specific `TargetRequest`. A `TargetProgram` then allows layout information and compiled kernel code to be asked for on-demand, in order to support eventual "live" compilation scenarios.
* The `EndToEndCompileRequest` type is a composition/coordination type that replaces the old `CompileRequest` in a way that uses the services of the various other types. It owns a few pieces of state that only make sense in the context of an end-to-end compile (e.g., there is really no way to "pass through" code when the front- and back-ends are run separately) or a command-line compile (everything to do with specifying output paths for files is really just for the benefit of `slangc`, and might even be moved there over time).
* One important detail is that the `EndToEndCompilRequest` owns all of the string-based generic arguments for both global and entry-point generic parameters. The logic in `check.cpp` for dealing with those arguments has been heavily refactored to separate out the parsings steps that are specific to end-to-end compilation with string-based type arguments, and the semantic checking steps that result in a specialized `Program` (which can be exposed through new APIs that aren't tied to end-to-end compilation).
It is perhaps not surprising that this change had a lot of consequences, so I'll briefly run over some of the main categories of changes required:
* I changed the way that global generic arguments are passed via API (use `spSetGlobalGenericArgs` instead of the generic arguments for `spAddEntryPointEx`, which are not just for entry-point generics), which has been a change that we've needed for a long time. This is technically a breaking API change, although we should have very few client applications that care about it.
* A bunch of places that used to take "big" objects like `CompileRequest` now just take the sub-pieces they care about (e.g., a function might have only needed a `Linkage` and a `DiagnosticSink`). This makes many subroutines or "context" struct types more generally useful, at the cost of taking more parameters.
* In a few cases the conceptually clean separation of the layers breaks down (often for edge-case or compatibility features), and so we may pass along additional objects that are allowed to be null, but are used when present. A big example of this is how the back-end code generation routines accept an `EndToEndCompileRequest` that is optional, and only used to check whether "pass through" compilation is needed. We should probably look into cleaning this kind of logic up over time so that we don't need to violate the apparent separation of phases of compilation.
* In cases where separation of layers was being broken for the sake of GLSL features, I went ahead and ripped them out, since all of that should be dead code anyway.
* In many cases I increased the encapsulation of data in the core types to help track down use sites and make sure they are following invariants better.
* In cases where code was doing, e.g., `context->shared->compileRequest->session->getThing()` I have tried to introduce convenience routines so that the usage site is just `context->getThing()` to improve encapsulation and allow changes to be made more easily going forward.
* The `noteInternalErrorLoc` functionality was moved off of the compile request and into `DiagnosticSink`, since that is the one type you can rely on having around when you want to note an internal error. We may consider going forward if (and how) it should reset the counter used for noting locations on internal errors.
* A few APIs now take `DiagnosticSink*` arguments where they didn't before, and as a result some public APIs need to create `DiagnosticSink`s to pass in, before going ahead and ignoring the messages. In the future there should be variations of these APIs that accept an `ISlangBlob**` parameter for the output.

Previously the IR codegen logic was treating function-scope `static const` variables just like `static` variables, which results in them generating less efficient output HLSL/GLSL.
This change special-cases function-local `static const` variables with logic that mirrors how we handle global-scope `static const` variables.
The approach in this change attempts to find a simpler solution to deal with `static const` variables inside of generic functions than what is currently done for `static` variables in generic functions, but I haven't tested whether that works in practice, so I didn't apply the same approach to the plain `static` case. That would make a good follow-on change.
I've included a single test case to demonstrate that with this fix the Slang compiler generates output DXBC that uses an indexable "immediate" constant buffer, whereas without the fix it generates an array in local memory (slow).

* Fix some subtle bugs in D3D constant buffer layout
The root of the issue here is that the D3D constant buffer layout rules require 16-byte alignment for arrays and structures, but they do *not* round up the size of an array/structure type to account for that alignment.
That means that in cases like the following:
```hlsl
cbuffer C0 { float3 a[2]; float c0; }
struct A { float4 x; float3 y; };
cbuffer C1 { A a; float c1; }
```
The `c0` and `c1` fields get an offset of 28 and not 32 like you might expect if the preceding array/structure field `a` had been padded out to match its 16-byte alignment.
The actual fix here is relatively simple, and mostly amount to shuffling around some code in `type-layout.cpp` to ensure that the D3D constant buffer layout don't inherit the logic that was rounding up array/structure sizes. Along the way I took the opportunity to clean up the inheritance hierarchy by making the GLSL-family layout rules not try to share anythign with the D3D family (not that there is very little to share), which in turn allowed for some simplification of the GLSL side of things.
Fixing this behavior changed the output of a few reflection tests. In the case of `tests/reflection/arrays.hlsl` the output confirmed that we had been producing bad reflection information in these kinds of cases. The output for `tests/reflection/matrix-layout.slang` also showed some bugs in our reflection, but these were overall more minor: we mis-reported the size of certain matrices as 64 bytes instead of 60, and as a result also computed the size of the overall constant buffer as 4 bytes bigger than needed. In all of these cases I double-checked the expected output against dxc to make sure that the new offsets/sizes are what we should have been producing in the first place.
I also updated the reflection test harness to start outputting layout information for the element type of a structured buffer, which changed the output of `tests/reflection/structured-buffer.slang`, but this didn't show any change in what we reported: it is just information that wasn't in the output to begin with.
Finally, I added two new tests around these subtle cases of buffer layout behavior (especially subtle because it varies across target APIs).
The `tests/compute/buffer-layout.slang` test simply sets up a type to ilustrate the troublesome scenarios and then embeds it in both a constant buffer and structured buffer that will be backed by memory with sequential `int` values. We then read out the value of a field as a way to probe its de facto *offset* at runtime. This test doesn't really stress the Slang compiler (except for our ability to pass through the same type declarations to downstream compilers), but it is useful to confirm our expectations about where things land in memory.
The `tests/reflection/buffer-layout.slang` test then uses the reflection test infrastructure to confirm that the same type declarations used in the compute test produce the expected offsets in our reported reflection information. Before the fixes in this change this test showed us producing dangerously incorrect results in our D3D reflection information, which has now been fixed to match the empirically-determined offsets from the compute test.
