Tyler Nowicki 842a06e8dd Add diagnostics to the vectorizer cost model. ...

When the cost model determines vectorization is not possible/profitable these remarks print an analysis of that decision.

Note that in selectVectorizationFactor() we can assume that OptForSize and ForceVectorization are mutually exclusive.
