LoopVectorize fix: LoopInfo must be valid when invoking utils like SCEVExpander. In general, one should always complete CFG modifications first, update CFG-based analyses, like Dominatores and LoopInfo, then generate instruction sequences. LoopVectorizer was creating a new loop, calling SCEVExpander to generate checks, then updating LoopInfo. I just changed the order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186241 91177308-0d34-0410-b5e6-96231b3b80d8
