  -----------
  [ObjCARC] Fix non-determinism

We often failed in the assertion, non-deterministically with a large IR:
```
Assertion `notDifferentParent(LocA.Ptr, LocB.Ptr) && "BasicAliasAnalysis doesn't support interprocedural queries."
```
Looking at the comment in https://reviews.llvm.org/D87806, it appears it's actually a module pass for new PM while the legacy PM still works as a function pass.
The fix is to align the same behavior in between new PM and old PM, which initializes ObjCARCContract for each function.
