Antonio Maiorano a8c202b8e7 HLSL: work around FXC failures when dynamically indexing matrices
This fixes errors like "error X3500: array reference cannot be used as
an l-value; not natively addressable". Note that FXC treats matrices
like arrays. We still get this error for dynamically indexed arrays in
structs.

Also improved HLSL assign tests, and add missing ones for vector
indexing.

Manually removed 20 e2e skip hlsl SKIP files that are now passing with
this change.

Antonio Maiorano 2f7730a16e Manually generate HLSL skip files for vk-gl-cts e2e tests
It seems we haven't run our e2e tests with FXC validation in a long time
 - at least not since we've added the vk-gl-cts corpus.

Locally disabled exclusion of "/test/vk-gl-cts/" in test-runner/main.go,
and ran:
./test/test-all.sh out/build/x64-Debug/tint.exe --format hlsl --fxc --generate-skip

These will need to be manually removed once the skips aren't needed by
deleting them all, and re-running as above.

James Price 87cce20f67 test: Remove many expected files
For these tests, we only really care that we can successfully consume
them and generate valid output for each backend. Having the expected
files in the tree generates significant churn for any change to how we
generate backend code, which makes it hard to inspect diffs.

James Price 11c6fcdb51 spirv: Use generic transform to process shader IO
The refactored CanonicalizeEntryPointIO transform makes it much easier
to handle SPIR-V style IO as well, and doing this removes a lot of
duplicated code. Remove all of the SPIR-V transform code for shader IO
and vertex point size.

James Price a5d73ce965 transform/shader_io: Generate a wrapper function
This is a major reworking of this transform. The old transform code
was getting unwieldy, with part of the complication coming from the
handling of multiple return statements. By generating a wrapper
function instead, we can avoid a lot of this complexity.

The original entry point function is stripped of all shader IO
attributes (as well as `stage` and `workgroup_size`), but the body is
left unmodified. A new entry point wrapper function is introduced
which calls the original function, packing/unpacking the shader inputs
as necessary, and propagates the result to the corresponding shader
outputs.

The new code has been refactored to use a state object with the
different parts of the transform split into separate functions, which
makes it much more manageable.

Corentin Wallez e33b0baa08 Revert "MSL writer: make signed int overflow defined behaviour"
This reverts commit e5dbe24e94.

Reason for revert: Makes the Tint-Dawn roll fails because of
MSL compilation errors on as_type<uint>(-2147483648):
as_type cast from 'long' to 'uint' (aka 'unsigned int') is not allowed
   
as_type<uint>(-2147483647) compiles fine, so this is most
likely because the MSL compiler types the literal as a long
(since without the - it is larger than the max int32).

Alastair Donaldson f7e73d4ee3 Add tests derived from VK-GL-CTS
This adds SPIR-V assembly and WGSL tests derived from VK-GL-CTS commit
571256871c2e2f03995373e1e4a02958d8cd8cf5. The following procedure was
followed:

- Those .amber files in VK-GL-CTS wholly owned by Google were
  identified

- All GLSL and SPIR-V shaders were extracted from the Amber files and
  converted into SPIR-V binaries

- The compact-ids pass of spirv-opt was applied to each binary

- Duplicate binaries were removed

- spirv-opt -O was used to obtain an optimized version of each remaining
  binary, with duplicates discarded

- Binaries that failed validation using spirv-val with target
  environment SPIR-V 1.3 were discarded

- Those binaries that tint could not successfully convert into WGSL were
  put aside for further investigation

- SPIR-V assembly versions of the remaining binaries are included in
  this CL

- test-runner with -generate-expected and -generate-skip was used to
  generate expected .spvasm, .msl, .hlsl and .wgsl outputs for these
  SPIR-V assembly tests

- Each successfully-generated .expected.wgsl is included in this CL
  again, as a WGLSL test

- test-runner with -generate-expected and -generate-skip was used again,
  to generate expected outputs for these WGSL tests
