1ed7f8ede564 <https://reviews.llvm.org/rG1ed7f8ede564c3b11da4fdca30c36ccbff422576> added support for pointer phis in AccessAnalysis.
This patch also applies the same logic to MemoryDepChecker, because
otherwise we might crash, because we do not have IR instructions
associated with analyzed pointers. I think the same reasoning as
in 1ed7f8ede564 <https://reviews.llvm.org/rG1ed7f8ede564c3b11da4fdca30c36ccbff422576> should also apply in this case: we effectively treating
the memory operations with pointer phi operands as if they execute once
for each incoming value.
Fixes PR50296, PR50288.
