We were previously using getFirstInsertionPt to insert PHI instructions when vectorizing, but getFirstInsertionPt also skips past landingpads, causing this to generate invalid IR. We can avoid this issue by using getFirstNonPHI instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191526 91177308-0d34-0410-b5e6-96231b3b80d8
