tree-vect-slp.c (vect_slp_bb): Dump MSG_OPTIMIZED_LOCATIONS here, also noting vector size used.

2018-06-15  Richard Biener  <rguenther@suse.de>

	* tree-vect-slp.c (vect_slp_bb): Dump MSG_OPTIMIZED_LOCATIONS
	here, also noting vector size used.
	* tree-vectorizer.c (vectorize_loops): Adjust.  Note vector
	size used in MSG_OPTIMIZED_LOCATIONS dump.
	(pass_slp_vectorize::execute): Adjust.
