[SPIR-V] Incorrect SPIR-V when using a global variable to access resources

[luciechoi]

SPIR-V validator fails when using accessing resources with a global variable

RWStructuredBuffer<uint> ReadWriteStructuredBuf[64];

uint i;

[numthreads(1,1,1)]
void main() {
    ReadWriteStructuredBuf[i][99] = 98;
}

Found from #162889

@luciechoi I cannot reproduce the problem. Can you provide the compile command I should use?

Sorry for the confusion, this was created because the validation step was failing for unit tests in #162889 but the problem was with my llvm ir. Created #164455
