* tree-vectorizer.h (stmt_vinfo_set_inside_of_loop_cost,

	stmt_vinfo_set_outside_of_loop_cost): New functions.
	* tree-vect-transform.c (vect_get_cost_fields): Remove.
	(vect_model_simple_cost): Call
	stmt_vinfo_set_inside/outside_of_loop_cost to set the relevant cost
	field instead of calling vect_get_cost_fields.
	(vect_model_store_cost, vect_model_load_cost): Likewise.
