LGTM.

As both the emission of the `IMPLICIT_DEF` instructions in SelectionDAG, and the resolving of those instructions in "Process Implicit Definitions", is target independent code, I think it would be sufficient with only keeping one of these test cases, but I would be fine with landed this with all five.
