Paul Redmond 5767d91956 Do not vectorize loops with subtraction reductions ... Since subtraction does not commute the loop vectorizer incorrectly vectorizes reductions such as x = A[i] - x. Disabling for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171537 91177308-0d34-0410-b5e6-96231b3b80d8		2013-01-04 22:10:16 +00:00
