Max Kazantsev 594cb55686 [NFC] Verify memoryssa in test for PR39783 
llvm-svn: 348333

Max Kazantsev 9cf417db78 [LoopSimplifyCFG] Update MemorySSA in terminator folding. PR39783 
Terminator folding transform lacks MemorySSA update for memory Phis,
while they exist within MemorySSA analysis. They need exactly the same
type of updates as regular Phis. Failing to update them properly ends up
with inconsistent MemorySSA and manifests in various assertion failures.

This patch adds Memory Phi updates to this transform.

Thanks to @jonpa for finding this!
