	stmt_vinfo_set_inside_of_loop_cost,
	stmt_vinfo_set_outside_of_loop_cost, vect_pow2, aligned_access_p,
	known_alignment_for_access_p): Likewise.
	* tree-vect-loop.c: Fix documentation.
	(vect_get_cost): Start function name from new line.
	* tree-vect-data-refs.c: Fix documentation.
	* tree-vect_stmts.c: Likewise.
	(vect_create_vectorized_promotion_stmts): Always free vec_tmp.
	(vectorizable_store): Free vec_oprnds if allocated.
	(vectorizable_condition): Initialize several variables to avoid
	warnings.
