tree-vect-loop.c (vect_compute_single_scalar_iteration_cost): Open a dump scope.

2018-10-08  Richard Biener  <rguenther@suse.de>

	* tree-vect-loop.c (vect_compute_single_scalar_iteration_cost):
	Open a dump scope.
	* tree-vectorizer.c (dump_stmt_cost): Add cost param and dump it.
	* tree-vectorizer.h (dump_stmt_cost): Adjust.
	(add_stmt_cost): Dump return value of the hook.
