I think one of the things we want in the new PM is the data locality that we see from iterating only specific IR units (functions in this case). This was brought up before when porting ASan (D54337 <https://reviews.llvm.org/D54337>). In this patch it also looks like the pass still goes over functions only. If there are other globals that this should pass over, could you add/update a test to show that?
