re PR tree-optimization/26420 (-ftree-vectorizer-verbose=1 prints unvectorized loops information)

PR tree-optimization/26420
* tree-vectorizer.c (vectorize_loops): Bail out early if there
are no loops in the function. Only print the number of
vectorized loops if it is greater than zero or we are supposed
to print information about unvectorized loops.
