Also Revert "[LoopVectorize] Fix non-debug builds after rL374017" This reverts commit 9f41deccc0e648a006c9f38e11919f181b6c7e0a. This reverts commit 18b6fe07bcf44294f200bd2b526cb737ed275c04. The patch is breaking PowerPC internal build, checked with author, reverting on behalf of him for now due to timezone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@374091 91177308-0d34-0410-b5e6-96231b3b80d8
