I don't quite see any other point to tweak the logic. We have some `amdgcn`
builtins that get handled here, as opposed to via `EmitTargetBuiltinExpr`, and
this is the narrowest scope for adjusting `Prefix`; the information that this
is coming from AMDGCN flavoured SPIRV is lost past this point. Did you have
something in mind regarding where to handle this as an alternative?
