Discovered while running the offload-test-suite. Hitting an assert when compiling this program with spirv:
```hlsl
StructuredBuffer<uint4> Low : register(t0);
StructuredBuffer<uint4> High : register(t1);
RWStructuredBuffer<double4> Out : register(u2);
[numthreads(1,1,1)]
void main() {
Out[0] = asdouble(Low[0], High[0]);
}
```
```
Assertion `DstType->getNumElements() >= SrcType->getNumElements()' failed
```
