  Log Message:
  -----------
  Reapply "[VPlan] Handle calls in VPInstruction:opcodeMayReadOrWriteFromMemory." (#191886)

This reverts commit
https://github.com/llvm/llvm-project/commit/3bf9639ec04544902670ab4199401ac470c1fcca.

The reapply adds trivial support for ExtractValue and InsertValue to fix
the crash causing the revert.

Original message:

Retrieve the called function and check its memory attributes, to
determine if a VPInstruction calling a function reads or writes memory.

Use it to strengthen assert in areAllLoadsDereferenceable.
