	* tree-vectorizer.h (_loop_vec_info): Add scalar_cost_vec
	and single_scalar_iteration_cost members.
	(LOOP_VINFO_SCALAR_ITERATION_COST): New.
	(LOOP_VINFO_SINGLE_SCALAR_ITERATION_COST): Likewise.
	(vect_get_single_scalar_iteration_cost): Remove.
	* tree-vect-data-refs.c (vect_peeling_hash_get_lowest_cost):
	Use LOOP_VINFO_SCALAR_ITERATION_COST.
	* tree-vect-loop.c (destroy_loop_vec_info): Free
	scalar_cost_vec.
	(vect_get_single_scalar_iteration_cost): Compute result into
	LOOP_VINFO_SINGLE_SCALAR_ITERATION_COST and
	LOOP_VINFO_SCALAR_ITERATION_COST.  Make static.
	(vect_analyze_loop_2): Call vect_get_single_scalar_iteration_cost.
	(vect_estimate_min_profitable_iters): Use them.
