[LoopLoadElim] Filter away candidates that stop being AddRecs after loop
versioning. PR47457
The test in PR47457 demonstrates a situation when candidate load's pointer's
SCEV
is no loger a SCEVAddRec after loop versioning. The code there assumes that it
is
always a SCEVAddRec and crashes otherwise.
This patch makes sure that we do not consider candidates for which this
requirement
is broken after the versioning.
