* Add a simple interface parameter test
Since there's no documentation, it's nice to have a simple test case in order to
experiment with this feature of the testing framework.
* Add shader entry point attributes to tests
* Fix specialization arguments for tests
- Add some missing arguments
- Rremove one extraneous argument.
* Stop using deprecated compile request in render-test
Use a session object instead of the deprecated compile request object.
This closes issue #4760.

* render-test: Add copy-source usage for render targets
I found that Slang-RHI/WGPU was not able to copy from render targets to staging buffers.
This helps to address issue #4943.
* Add entries to render API util infos
Entries for glsl-cross and glsl-rewrite are added.
Without glsl-cross, slang-test fails to select a back-end, and winds up crashing when
tests/render/cross-compile-entry-point.slang is enabled
tests/render/cross-compile0.hlsl fails similarly without glsl-rewrite.
* Enable some rendering tests
* Add expected test outputs

* Remove old code paths from render-test
Historically, the `render-test` tool was using three different code paths:
* One based on `gfx` and manual (non-reflection-based) parameter setting, used for OpenGL, D3D11, D3D12, and Vulkan
* One for CPU that used reflection-based parameter setting but shared no code with the first
* One for CUDA that used reflection-based parameter setting and shared some, but not all, code with the CPU path
Recently we've updated `render-test` to include a fourth option:
* Using `gfx` and the "shader object" system it exposes for a unified reflection-based parameter-setting system taht works across OpenGL, D3D11, D3D12, Vulkan, CUDA, and CPU
This change removes the first three options and leaves only the single unified path. A sa result, a bunch of code in `render-test` is no longer needed, and the codebase no longer relies on things like the `IDescriptorSet`-related APIs in `gfx`.
Several existing tests had to be disabled to make this change possible. Those tests will need to be audited and either re-enabled once we fix issues in the shader object system, or permanently removed if they don't test stuff we intend to support in the long run (e.g., global-scope type parameters, which aren't a clear necessity).
* fixup: CUDA detection logic

* Dx12 rendering works in test framework.
* Turn on dx12 render tests.
* Getting simpler dx12 compute tests to work.
* With expected data in test - check for specialized and then for the default, so that multiple test can share the same expected data, but specialized cases can still be set.
* Fixed construction and binding on dx12 textures.
* Control which render apis used in test from command line.
* Small aesthetic fixes in render-test/main.cpp.
* Fix binding problem for uavs/srvs dx12. Previously tried to create srv/uav for StorageBuffers (like dx11 does), but the binding breaks as you can end up with two srvs using the same register.
First pass at fixing problems with Texture creation for dx12 - assertions were hit with 3d or array textures.
* Fixes to improve Dx12 setup shader resource views for cubemaps/arrays.
* Fixed d3d12 textureSamplingTest - problem was that cubemap/array textures were not being uploaded correctly.
* Changed the order of how binding of constant buffers (as just set on the Renderer) indexes. Previously they were given the lowest indices, but they clashed with the indices from the 'Binding'. Changing this means all tests run on d3d12.
* Add code to allow use of warp (although not command line switchable yet).
Fix problem setting up raw UAV - as identified by warp.
* Added RenderApiUtil - which can detect if a render api is potentially available.
* Moved render flag testing/parsing into RenderApiUtil.
* Fix signed/unsigned warning.
* Fixes around enums prefixed with k on the review of feature/dx12 compute branch.
* Remove explicit -dx12 line in tests, as all can currently be generated from dx11 tests.

Fixes #350
When the Slang project forked off from the Spire research effort, we renamed things as we went, but many cases seem to have slipped through the cracks.
The two biggest diffs here are:
- The `hello` example program was incorrectly talking about what was in the shader file (Slang no longer supports the "module" or "pipeline" constructs from Spire), and so it wasn't just a simple rename.
- The files under `tests/bindings` were mistakenly using `__SPIRE__` as a preprocessor guard, which means that they weren't actually testing what they meant to. Luckily, it looks like the relevant functionality didn't regress while these tests were unintentionally deactivated.

The basic change is simple: remove support for all code generation paths other than the IR.
There is a lot of vestigial code left, but the main logic in `ast-legalize.*` is gone.
Doing this breaks a *lot* of tests, for various reasons:
- We can no longer guarantee exactly matching DXBC or SPIR-V output after things pass through out IR
- Many builtins don't have matching versions defined for GLSL output via IR (even when they had versions defined via the earlier approach that worked with the AST)
- A lot of code creates intermediate values of opaque types in the IR, which turn into opaque-type temporaries that aren't allowed (this breaks many GLSL tests, but also some HLSL)
I implemented some small fixes for issues that I could get working in the time I had, but most of the above are larger than made sense to fix in this commit.
For now I'm disabling the tests that cause problems, but we will need to make a concerted effort to get things working on this new substrate if we are going to make good on our goals.

* Remove support for the -no-checking flag
Fixes #381
Fixes #383
Work on #382
- No longer expose flag through API (`SLANG_COMPILE_FLAG_NO_CHECKING`) and command-line (`-no-checking`) options
- Remove all logic in `check.cpp` that was withholding diagnostics (including errors) when the no-checking mode was enabled
- Remove `HiddenImplicitCastExpr`, which was only created to support no-checking mode (it represented an implicit cast that our checking through was needed, but couldn't emit because it might be wrong)
- Remove logic for storing function bodies as raw token lists when checking is turned off. I'm leaving in the `UnparsedStmt` AST node in case we ever need/want to lazily parse and check function bodies down the line.
- Remove a few of the code-generation paths we had to contend with, but keep the comment about them in place.
- Remove GLSL-based tests that can't meaningfully work with the new approach.
- Fix other tests that used a GLSL baseline so that their GLSL compiles with `-pass-through glslang` instead of invoking `slang` with the `-no-checking` flag.
- Remove tests that were explicitly added to test the "rewriter + IR" path, since that is no longer supported.
There is more cleanup that can be done here, now that we know that AST-based rewrite and IR will never co-exist, but it is probably easier to deal with that as part of removing the AST-based rewrite path.
We've lost some test coverage here, but actually not too much if we consider that we are dropping GLSL input anyway.
* Fixup: test runner was mis-counting ignored tests
* Fixup: turn on dumping on test failure under Travis
* Fixup: enable extensions in Linux build of glslang

* Rename `lower.{h,cpp}` to `ast-legalize.{h,cpp}`
This pass isn't really performing lowering akin to `lower-to-ir.{h,cpp}` so the file name is misleading.
By renaming this pass we emphasize its role as an AST-related pass.
Also update the comment at the top of `ast-legalize.h` to reflect the intended purpose of this pass in a world where we have the IR up and running.
* Allow `import` as an alias for `__import`
The use of double underscores to mark our new syntax has so far had two purposes:
1. It helps identify syntax that isn't meant to be exposed to users in its current form (e.g., `__generic` gets a double underscore because we want users to have a more pleasant surface syntax for generics that they write). This rationale doesn't apply to `__import`, which is a major language feature that users need to interact with.
2. It helps avoid the problem where the compiler treats something as a keyword that isn't supposed to be reserved in HLSL/GLSL and so causes existing user code to fail to parse (e.g., when the user tries to write a function called `import`). This no longer matters because we look up almost all of our keywords using the existing lexical scoping in the language (so the user can shadow almost any keyword with a local declaration).
So, neither of the original two reasons applies to `__import`, and it makes sense to expose it as `import`.
Doing so is a one-line change.

- Allow a code-generation target of `NONE` in order to suppress ordinary output in test cases where we don't care about the actual output (just pass/fail result)
- Add explicit `location` layout qualifiers to intermediate vertex-to-fragment variables in GLSL test cases for rendering, to work around apparent Intel driver bugs.

This includes a bunch of related changes:
- `slang-test`
- Add a notion of an "output mode" that specifies whether we output to console (the default), or invoke the apprpriate AppVeyor command to update test status
- Add a notion of test categories, so that tests can be tagged with categories, and then we can invoke only those tets in a given category, or choose to *exclude* tests with specific categories
- Allow the `OSProcessSpawner` to look up an executable by "path" (meaning a full path is expected) or by "name" (meaning it should be allowed to look in the current directory, `PATH` environment variable, etc.). This was important to make sure that I can run `appveyor` without having to know its absolute path.
- AppVeyor configuration
- Change badge to reflect new build account for organization (rather than a single-user account)
- Remove attempt to set AppVeyor build version in a clever way, since it breaks links from GitHub to AppVeyor
- Change order or configurations in the build matrix to front-load the Release build (which has the main tests)
- Turn on `fast_finish` flag so we don't have to wait as long for failed builds
- Turn on `parallel` builds
- Set `verbosity: minimal` to avoid getting build spew about Xamarin stuff I'm not using
- Add custom `test_script` to invoke `test.bat`
- Sets the test category based on teh build configuration, so we don't run the full test suite on every input.
- `test.bat`
- Allow for `-platform` and `-configuration` arguments
- Rewrute a platform of `Win32` over to `x86` to match how the output directories are named
- Futz around with how the directories are being passed along to work around annoying `.bat` file quoting behavior (I still don't get how batch files work)
- Tests
- Mark a bunch of tests as `smoke` tests
- Mark the relevant tests as `render` tests
(these get filtered out for AppVeyor builds)

This is a large change that contains many pieces:
- Update the `cross-compile0` test to actually make use of cross compilation.
Now the `cross-compile0.hlsl` file contains both HLSL and GLSL source code, and then imports code from `cross-compile0.slang`, which provides a "library" (one function) that can be shared between both the HLSL and GLSL version of things.
- Fixed a bug in the support for backslash-escaped newlines.
- Added a new `__import` declaration type (replaces the `using` directive that was still around in a vestigial form)
An `__import` causes the compiler to look for a Slang source file (currently using the ordinary `#include` lookup logic), and then parse/check the found file as an additional module ("translation unit"), before making its declarations visible in the current scope.
- Refactored the main compilation flow to be simpler. There were the `ShaderCompiler` and `ShaderCompilerImpl` classes that weren't relaly doing anything, but added complexity to the whole workflow.
- The `render-test` application has been heavily modified to better support testing cross-compilation workflows. At the most basic level we are starting to distinguish pass-through vs. rewriter workflows, and are passing various `#define`s down to the compiler(s) to let the source code be customized as needed for each case.
Several annoying corner cases are caused here by having to support the GLSL compilation model, which really wants each entry point in its own specific translation unit, whereas we really want to keep things nicely contained in single files.
- Added support for `__intrinsic` operations to have target-specific behavior.
This allows a function to be given a different name for some specific target (so a call gets emitted as a call to that other operation).
More generally, the library writer can put together an arbitrary format string that will be used in place of expressions that call the given function, e.g.:
__intrinsic(hlsl, "$1 - $0") __intrinsic int foo(int a, int b);
Given this declaration, a call like `foo(x,y)` will code generate as `x - y` for HLSL, and as `foo(x,y)` for all other targets.
Annoying things still to be dealt with:
- The way that I'm filtering the user-provided options when passing things down to the compilation of dynamically loaded modules is a bit ad hoc. It would be good to have a systematic notion of which options will be inherited and which won't. There is also more code duplication than I'd like, so we risk having the compiler behave differently when compiling a file at the top level, vs. because of `__import`.
- Adding target-specific behavior to intrinsics is all well and good, but the current approach means we can only add this to the original declaration, which limits the ability to easily extend the set of targets.
A better approach long-term would be to add a more robust notion of target-based overload resolution (which would happen after semantic checking). Then one mechanism would be used to find the right target-specific overload to use for an operation, and then each (target-specific) definition could use a simpler attribute to intercept code-generation behavior.
Note that we might eventually need a similar notion to deal with stage- or profile-specific functions and the overloading behavior around them, so using this for intrinsics doesn't seem like a bad idea.

The test case that is there right now is nominally a cross-compilation test, but for right now it uses the preprocessor to present completely different code for HLSL and GLSL compilation.
This change is really just fleshing out the OpenGL side of `render-test` enough that it can produce images using OpenGL to enable further testing.
