  Changed paths:
    M llvm/include/llvm/Analysis/MemorySSA.h
    M llvm/lib/Analysis/MemorySSA.cpp
    M llvm/test/Analysis/MemorySSA/phi-translation.ll

  Log Message:
  -----------
  [MemorySSA] Restrict optimizations after a PhiTranslation.

Merging alias results from different paths, when a path did phi
translation is not necesarily correct. Conservatively terminate such paths.
Aimed to fix PR46156.
