	* tree-data-ref.h (find_data_references_in_loop): Declare.
	* tree-data-ref.c (get_references_in_stmt): Use a stack
	vector pre-allocated in the callers.
	(find_data_references_in_stmt): Adjust.
	(graphite_find_data_references_in_stmt): Likewise.
	(create_rdg_vertices): Likewise.
	(find_data_references_in_loop): Export.
	* tree-vect-data-refs.c (vect_analyze_data_ref_dependences):
	Compute dependences here...
	(vect_analyze_data_refs): ...not here.  When we encounter
	a non-vectorizable data reference in basic-block vectorization
	truncate the data reference vector.  Do not bother to
	fixup data-dependence information for gather loads.
	* tree-vect-slp.c (vect_slp_analyze_bb_1): Check the number
	of data references, as reported.
