[SelectionDAG] Propagate scoped AA metadata when lowering mem intrinsics.
- When memory intrinsics, such as memcpy, the attached scoped AA
metadata is not passed down to the backend. As a result, the backend
cannot schedule relevant memory operations around them following that
hint. In this patch, SelectionDAG is enhanced to propagate that
metadata (scoped AA only) when they are lowered into loads and stores.
