* Fix premake5.lua so it uses the new path needed for OpenCLDebugInfo100.h
* Keep including the includes directory.
* Added the spirv-tools-generated files.
* We don't need to include the spirv/unified1 path because the files needed are actually in the spirv-tools-generated folder.
* Put the build_info.h glslang generated files in external/glslang-generated. Alter premake5.lua to pick up that header.
* First pass at documenting how to build glslang and spirv-tools.
* Improved glsl/spir-v tools README.md
* Added revision.h
* Change how gResources is calculated.
Update about revision.h
* Update docs a little.
* Split out spirv-tools into a separate project for building glslang. This was not necessary on linux, but *is* necessary on windows, because there is a file disassemble.cpp in spirv-tools and in glslang, and this leads to VS choosing only one. With the separate library, the problem is resolved.
* Fix direct-spirv-emit output.
* Update to latest version of spirv headers and spirv-tools.
* Upgrade submodule version of glslang in external.
* Add fPIC to build options of slang-spirv-tools
* WIP adding support for InterlockedAddFp32
* Upgrade slang-binaries to have new glslang.
* Fix issues with Windows slang-glslang binaries, via update of slang-binaries used.
* WIP - atomicAdd. This solution can't work as we can't do (float*) in glsl.
* WIP on atomic float ops.
* Added checking for multiple decls that takes into account __target_intrinsic and __specialized_for_target.
First pass impl of atomic add on float for glsl.
* Split __atomicAdd so extensions are applied appropriately.
* Made Dxc/Fxc support includes.
Use HLSL prelude to pass the path to nvapi
Added -nv-api-path
* Refactor around IncludeHandler and impl of IncludeSystem
* slang-include-handler -> slang-include-system
Have IncludeHandler/Impl defined in slang-preprocessor
* Small comment improvements.
* Document atomic float add addition in target-compatibility.md.
* CUDA float atomic support on RWByteAddressBuffer.
* Add atomic-float-byte-address-buffer-cross.slang
* Removed inappropriate-once.slang - the test is no longer valid when a file is loaded and has a unique identity by default. A test could be made, but would require an API call to create the file (so no unique id).
Improved handling of loadFile - uses uniqueId if has one.
* Work around for testing target overlaps - to avoid exceptions on adding targets.
Simplify PathInfo setup.
Modify single-target-intrinsic.slang - it no longer failed because there were no longer multiple definitions for the same target.

* Backend for Multiple Entry Points
Introduces the basic backend on the compiler for zero or more entry
points. Entry points have been extended to lists for several functions,
with loopFunctions have been extended to take in entry points and
indices as appropriate, to allow for multiple entry points once the
frontend is expanded. Several functions are currently being assumed to
have a single entry point for simplicity and provide a work in progress
commit.
* Progress on debugging fixes
* Tests passing
* Refactored emitEntryPoints
* Updated lists to be by constant reference
* Fixes to formatting
* Refactoring updates for the compiler
* Fix for compilation errors
* Reformatting
* More reformatting
* Moved struct around to help with compilation

* Initial work on representing layout at IR level
This change starts the process of making the back-end of the compiler independent of the AST-level layout information (`TypeLayout`, `VarLayout`, etc.) so that it instead only relies on layout information that is embedded into IR modules. This brings us incrementally closer to a world in which the back-end could be run without the AST-level structures even existing (e.g., for an application that just wants to ship IR without any AST information for IP protection, while still supporting some amount of linking and specialization).
The main parts of the change are:
* There is a bunch of incidental churn related to specifying entry points by index instead of the `EntryPoint` object for certain operations. This ends up being a better choice because we can use the index to look up side-band information about the entry point that might not be stored on the `EntryPoint` object itself. In particular...
* We expand the `ComponentType` interface to support looking up the mangled name of an entry point by index. In common cases (no generic/interface specialization) this would be the same as asking the `EntryPoint` for its mangled name, but in cases where we have specialized a generic entry point, the mangled name would include speicalization arguments that are only available on the `SpecializedComponentType` that wraps the entry point. This part of the change isn't ideal and there might be a better solution waiting to be invented. Note that we store mangled entry point names as strings rather than using `DeclRef`s because that ensures that the information could be serialized and deserialized without a dependence on the AST.
* The `TargetProgram` type (which represents binding a specific `ComponentType` for a shader program to a specific `TargetRequest` that represents the target platform) is expanded to include an `IRModule` that represents layout information, in addition to the AST-level `ProgramLayout` it already contained. We create both of these objects at the same time (on-demand) to simplify the overall flow (so that any code that triggers creation of the AST-level layout will also ensure that the IR-level layout exists).
* A bunch of code in the emit passes that was passing down layout-related objects has been eliminated. It appears that most of those objects weren't actually being used, so this is just a cleanup, but it helps ensure that the back-end steps are "clean" and don't depend on the AST-level information. The one big exception here is that the emit logic needs to know the stage for the entry point being emitted (to deal with one wrinkle in translating DXR to VKRT).
* A big change (actually introduced by @jsmall-nvidia in a branch that this change copied and then built from) is to introduce some more explicit IR instructions to represent layout information, notably an `IRTypeLayout` and an `IRVarLayout`. For now these objects still reference their AST equivalents, but the separation gives us an incremental path to move information from the AST-level objects over to the IR ones. This work includes logic in `IRBuilder` to construct the IR-level layout objects from the AST-level ones on-demand, so that the existing code paths that try to attach AST-level layout will continue to work for now.
* Because layout information is now embedded in the IR, the `slang-ir-link.cpp` logic loses a lot of cases that used to deal with attaching AST-level layout objects to IR-level instructions during the linking process. Instead, the linker now assumes that one (or more) of the input IR modules will have layout information associated with it, and the linker makes sure to copy layout decorations (and the instructions they reference) from the input IR module(s) to the output using its more ordinary mechanisms.
* Inside `slang-lower-to-ir.cpp`, we add logic to construct an IR module in a `TargetProgram` that simply references the global shader parameters, entry points, etc. and attaches IR layout decorations to them. This is akin to the existing pass in the same file that constructs IR to represent specialization information, and both of these passes share infrastructure with the main AST->IR lowering pass. Eventually, it is expected that this pass will encompass more of the logic for copying AST-level layout information over to IR-level equivalents.
* One small wrinkle with this change was that the output for an HLSL generation test case changed some of its `#line` directives. The old code was actually more inaccurate than the new, so this change just updated the baseline. It also added some logic in the linker to make sure that when an IR instruction has multiple definitions, we try to pick up a source location from any of them, in case the "main" one somehow didn't get a location.
* Another small fix was that the key/value map in `StructTypeLayout` for mapping fields/members to their layouts was keyed on `Decl*` when it really should have been `VarDeclBase*`.
This change should in principle be a pure refactoring with no functionality changes, so no new tests were added. It is unfortunately also a change that has a high probability of breaking at least *some* client code, so we may want to be defensive and mark this with a new major version number (well, a new *minor* version number since we are pre-`1.0`) to give us some room for releasing hotfixes to the old version if needed.
