2320cddf - Reapply "[GVN] memoryssa implies no-memdep (#149473)" (#149767)

Reapply "[GVN] memoryssa implies no-memdep (#149473)" (#149767) Enabling one of MemorySSA or MD implies the other is off. Already approved in https://github.com/llvm/llvm-project/pull/149473 but I had to revert as I missed updating one test.
