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.
