I think this might be problematic. Whilst using i8 vectors with for vmfloat8_t
is mostly an implementation detail I don't think the same holds for scalar
types.
The problem with using i8 as the backing type is that it means data will be
passed via GPRs instead of FPRs, which is an ABI decision. If the intent is for
such types to be passed via FPRs then I suspect the clang side of things might
have to wait until we've got the LLVM side covered.
