Clang currently crashes when compiling the following simplified compute shader:
```hlsl
typedef uint4 uint32_t4;
typedef uint32_t4 uint32_t8[2];
uint32_t Accumulate(uint32_t8 V) {
uint32_t4 SumVec = V[0] + V[1];
return SumVec.x + SumVec.y + SumVec.z + SumVec.w;
}
Buffer<uint4> Buf;
RWBuffer<uint> Out;
[numthreads(8,1,1)]
void main(uint GI : SV_GroupIndex) {
uint32_t8 Val = {Buf[GI], Buf[GI+8]};
Out[GI] = Accumulate(Val);
}
```
