9a6c6a3736 LoopVectorizer: When we vectorizer and widen loops we process many elements at once. This is a good thing, except for 
small loops. On small loops post-loop that handles scalars (and runs slower) can take more time to execute than the
rest of the loop. This patch disables widening of loops with a small static trip count.
