* Implement separate downstream library interface
Create a new com interface to house the methods for
precompiling slang modules to target code.
Add methods to count dependent modules and scrape
them for downstream target binaries such that the
downstream target binaries are linkabe outside
of slang, e.g. via spirv-link or dxc.
Fixes #5147
* Rename to _Experimental
Clearly identify this as an interface subject to change.

Closes #5201
Currently ci.yml builds slang-llvm all the time for all platforms.
Because it takes too long, we store the output files in the cache.
If the cache server is too busy, slang-llvm will be rebuilt, which will take awhile, but it will eventually work out.
The problem is that git-clone was failing for cloning the LLMV repo.
This is a less expected result, because cloning a git repository normally don't fail.
We think that when the git-clone command is manually executed, there might be limit on the network connection based on IP or some sort.
We expect that this problem will be resolved if we use actions/checkout in the workflow.
Also this commit uses a forked repo of llvm under shader-slang
organization to avoid network traffic on the original llvm repo.

* Add path to bash to GITHUB_PATH
This is a workaround for a problem that keeps reoccurring on one of our self-hosted machines.
Ideally, we should assume that bash shell is available on the runner system, and we should rely on the system-wise setting of PATH to find bash.
This commit is a workaround for a case where bash cannot be found from the runner machine, which shouldn't be a case in a normal situation. It is also not safe to assume that the location of where bash is at a fixed location, because it can vary by how the system is setup.
Once we root cause the issue on the SlangWin4-2, we may remove this workaround later.

This commit enables the workflow debug message for running VK CTS
workflow.
Currently three CTS tests are causing a crash of deqp with an exit code
1. And when the debug message printing is enabled, this crash is no
longer happening, which is unexpected. It seems like the issue is on the
CI runner process rather than Slang, driver nor deqp.
We will keep the log message enabled not only to avoid the crash but
also to see more information when things went wrong.
This commit also prints the last 1,000 lines of TestResults.qpa when
deqp had a failing test or deqp was exited unexpectedly. This will help
us to debug the problem faster.

Closes #5117
This adds a build step of WebAssembly version of Slang.
Currently it is enabled only for Linux/Release to reduce the time cost
of CI, but the builds were all successful on all platforms and
configurations when tested.

* Implement texture_storage_Xd in WGSL
This commit implements `texture_storage_Xd` in WGSL, which is similar
to RWTextureXD in HLSL.
It is intresting that `texture_storage_Xd` doesn't take the shader
type as its input argument at all.
Instead, it takes "texel format" enum value as its first template
parameter, which can be found here:
https://www.w3.org/TR/WGSL/#storage-texel-formats
As an example, `texture_storage_2d<rg32uint, read_write>` expects
vec4<u32> as a value type for `Load` and `Store`, where Z-component
will be ignored and treated as zero and W-component will be treated
always as 1. The type `u32` is inferred from the enum value `rg32uint`.
Note that the number of component is always fixed to 4 regardless how
many components are actually stored.

* WGSL texture support for depth and multisampled
This commit fixes a few issues with WGSL texture intrinsics.
- static_assert-s are corrected.
- Gather functions work properly with depth textures
- Load functions work properly with depth textures and multisampled
textures

* Compile fixes for Wasm
The issues are all are due to 'long' types being 32 bits on WASM.
- class members redeclared errors
- << with StringBuilder and unsigned long is ambiguous
This helps to address issue #5115.
* Use the host executable suffix for generators
Since the generators are run at build-time, we should not use CMAKE_EXECUTABLE_SUFFIX,
which is the suffix for the target platform.
Instead, define CMAKE_HOST_EXECUTABLE_SUFFIX as appropriate, and use that suffix instead.
This helps to address issue #5115.
* Add support for Wasm as a platform
This helps to address issue #5115.
* Add emscripten build
This closes #5115.

`$p` was incorrectly removed on the previous commit.
This commit brings it back and fixes the problem.

This PR implements the texture gather functions for WGSL.
The pattern was very similar to how Metal was implemented.
Before copy and paste from the Metal implementation, I had to
clean up the Metal implementation to make it more readable
and maintainable.
Gather functions are available only for 2D and 3D textures.
Their `array` and `depth` variants may or may not be supported depending on the target.
`static_assert` ensures that Gather functions are available only for 2D and 3D textures.
Removed incorrect use of "$p" argument for targeting GLSL.

Closes #5143
Recently there was a commit that changed the behavior of the memory
pointer for WGSL.
This commit fixes some issues came up after the change.

This commit implements all of the texture intrinsics for WGSL except "Gather" and sampler-less.
They will be implemented in a separate PR.
A few things to note:
- texture sampling functions are available only for the fragment shader stage; not for compute
- WGSL doesn't have any functions similar to CalculateLevelOfDetail or CalculateLevelOfDetailUnclamped.
- WGSL doesn't have a function overlaoding for textureSample with "clamp" or "status" arguments.
- WGSL doesn't support Load operation with offset for texture_multisampled_XX and texture_storage_XX.
- WGSL supports only four types of depth textures: 2D, 2D_array, cube and cube_array.
- WGSL doesn't support "offset" variants for cube and cube_array.
