Philip Reames c3b3aa277a Fix a missing MemorySSA update in breakLoopBackedge ...

This is a case I'd missed in 6a8237. The odd bit here is that missing the edge removal update seems to produce MemorySSA which verifies, but is still corrupt in a way which bothers following passes. I wasn't able to reduce a single pass test case, which is why the reported test case is taken as is.
