Sebastian Pop 4b2d615774 [DA] use alias analysis cross iteration mode (#116628) ...

This patch fixes two bugs:
https://github.com/llvm/llvm-project/issues/41488
https://github.com/llvm/llvm-project/issues/53942

The dependence analysis assumes that the base address of array accesses
is invariant across loop iterations. In both bugs the base address
evolves following loop iterations: the base address flip-flops between
two different memory objects.

The patch uses the cross iteration mode of alias analysis to disambiguate the
base objects.
