Performs output validation with spirv-val for SPIR-V (as before), HLSL validation with DXC, and MSL validation with the Metal Shader Compiler. Disable HLSL tests that fail to validate Bug: tint:812 Change-Id: If78c351b4e23c7fb50d333eacf9ee7cc81d18564 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/51280 Reviewed-by: Antonio Maiorano <amaiorano@google.com> Reviewed-by: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
