Const correctness for gather-scatter info

The following adds const qualification to gather_scatter_info *
parameters for various APIs in the vectorizer.

	* tree-vect-stmts.cc (check_load_store_for_partial_vectors):
	Make *gs_info const.
	(vect_build_one_gather_load_call): Likewise.
	(vect_build_one_scatter_store_call): Likewise.
	(vect_get_gather_scatter_ops): Likewise.
	(vect_get_strided_load_store_ops): Likewise.
