[Clang] Implement function attribute nouwtable
To have finer control of IR uwtable attribute generation. For target code generation,
IR nounwind and uwtable may have some interaction. However, for frontend, there are
no semantic interactions so the this new `nouwtable` is marked "SimpleHandler = 1".
