NFC: Add a test to LV showing that reduction is not possible when reduction var is reset in the loop Added a test case to reduction showing where it's illegal to identify vectorize a loop. Resetting the reduction var during loop iterations disallows us from widening the dependency cycle to VF, thereby making it illegal to vectorize the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@339605 91177308-0d34-0410-b5e6-96231b3b80d8
