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.

Move the loop vectorizer from O2 to O3. It looks like the increase in code size actually hurts the performance on many programs.
