anna requested review of this revision.
Herald added a project: LLVM.

Since LICM has now unconditionally moved to MemorySSA based form, all
passes that run in same LPM as LICM need to preserve MemorySSA (i.e. our
downstream pipeline).

Added loop-mssa to all tests and perform -verify-memoryssa within
LoopPredication itself.
