When explicitly casting a matrix to a vector, an assertion is hit saying "Matrix types not yet supported in HLSL"
https://godbolt.org/z/681rYvbjb
```hlsl
export float4 fn(float2x2 m) {
float4 v = (float4) m;
return v;
}
```
```
clang: warning: argument unused during compilation: '-Qembed_debug' [-Wunused-command-line-argument]
