[SPIR-V] A number of boolean vector tests in the offload test suite started failing the same way

SPIRV-Tools commit id: fbe4f3ad913c44fe8700545f8ffe35d1382b7093
SPIRV-Headers commit id: 04f10f650d514df88b76d25e83db360142c7b174

This is very odd because I don't see these tests erroring in the offload test suite CI machines but I do see them failing locally. The commits all seem really new so its a mystery.

dxc-3.7 --version
libdxcompiler.so: 1.10(5201-3e6e1485)(1.9.0.15201)

The commit id of the binary matches git (3e6e148).

CLI command: <DXC_BUILD_DIR>/bin/dxc-3.7 -spirv -fspv-target-env=vulkan1.3 -T cs_6_5 -Fo source.tmp.o source.hlsl

@bogner to attempt to reproduce to narrow down why this is only happening in some places.
