aa13ea4ca0 [PM] Avoid getResult on a higher level in LoopAccessAnalysis 
Note that require<domtree> and require<loops> aren't needed because they
come in implicitly via the loop pass manager.

fe0b6a7f50 Fix LoopAccessAnalysis when potentially nullptr check are involved 
Summary:
GetUnderlyingObjects() can return "null" among its list of objects,
we don't want to deduce that two pointers can point to the same
memory in this case, so filter it out.
