[HLSL] XFAIL smoothstep.ll and SV_GroupIndex.ll SPIR-V backend tests

[kmpeng]

When SPIRV-Tools is enabled, tests that specify the target environment vulkan1.3 in the validation step fail. This is because SPIRV-Tools seems to have grown some capability checks for vulkan 1.3. The failing tests are:

• CodeGen/SPIRV/hlsl-intrinsics/SV_GroupIndex.ll
• CodeGen/SPIRV/hlsl-intrinsics/smoothstep.ll

For now, the fix is to XFAIL these tests to unblock the pipeline.

Issue #136344 tracks the long-term solution for this.

Changes

Temporarily fixes #136049.

SPIRV-Tools seems to have grown some capability checks for vulkan 1.3, which broke:

• CodeGen/SPIRV/hlsl-intrinsics/SV_GroupIndex.ll
• CodeGen/SPIRV/hlsl-intrinsics/smoothstep.ll

For now the fix is to XFAIL these tests to unblock the pipeline.
