Hmm looks like the testing reveals another problem. We have no way of
invalidating a platform specific constraint that also uses `{}`.
The AMDGCN tests expect `{exec}a` to fail to verify, but it does not fail in
the generic `validateHardRegisterAsmConstraint` since we want to support
something like `{r1}r`.
@AlexVlx I couldn't find any documentation on the usage of `{}` on AMDGPU, is
failing the constraint `{exec}a` necessary? If so, we might have to also reject
`{r1}r`.
