Turns out that things actually go slightly wrong earlier during LSR. LSR did not pass MSSU to SplitCriticalEdge, which caused the MemoryPhi to have slightly wrong incoming blocks. I pushed a fix for that, as it is straight-forward to fix (57ae9bb9323548b2ad4ba8274c3910bf9c764983 <https://reviews.llvm.org/rG57ae9bb9323548b2ad4ba8274c3910bf9c764983>). With that, this patch is no longer needed for the test case.
