This change showed up as a significant compile-time regression (before it was reverted): https://llvm-compile-time-tracker.com/compare.php?from=85ccdcaa502ee2c478f2d0ba2b1e217117b69032&to=d4ba28bddc89a14885218b9eaa4fbf6654c2a5bd&stat=instructions

>From what I understood, the usage of MemorySSA in LoopSink is still supposed to be behind a flag, so this seems unexpected to me?
