HLSL allows implicit truncation of vector types, but DXC warns about it. Clang needs to learn this warning.
```
StructuredBuffer<int4> In : register(t0);
RWStructuredBuffer<int> Out : register(u0);
[numthreads(4,2,1)]
void main(uint GI : SV_GroupIndex) {
Out[GI] = In[GI]; // expected-warning{{implicit truncation of vector type}}
}
```
