I found a problem with this. getIntrinsicForGCCBuiltin / Clang uses Triple::getArchTypePrefix(), which is “r600” when looking for the GCCBuiltin. It never finds the ones with AMDGPU as the target prefix, so to support both of these prefixes clang would need to specially handle these to support both __builtin prefixes
