Today clang will error with `error: single subscript expressions are not allowed for matrix values`.
But DXC does a vector load
https://hlsl.godbolt.org/z/PM46xW89v
```hlsl
RWStructuredBuffer<int> In;
RWStructuredBuffer<int> Out;
cbuffer Constants {
uint row;
uint col;
};
[numthreads(1, 1, 1)]
void CSMain(uint GI : SV_GroupIndex) {
int2x3 M = int2x3(0, 1, 2,
3, 4, 5);
Out[0] = M[row].x;
}
```
