	* tree-vect-data-refs.c (vect_update_interleaving_chain): Remove.
	(vect_insert_into_interleaving_chain): Likewise.
	(vect_drs_dependent_in_basic_block): Inline ...
	(vect_slp_analyze_data_ref_dependence): ... here.  New function,
	split out from ...
	(vect_analyze_data_ref_dependence): ... here.  Simplify.
	(vect_check_interleaving): Simplify.
	(vect_analyze_data_ref_dependences): Likewise.  Split out ...
	(vect_slp_analyze_data_ref_dependences): ... this new function.
	(dr_group_sort_cmp): New function.
	(vect_analyze_data_ref_accesses): Compute data-reference groups
	here instead of in vect_analyze_data_ref_dependence.  Use
	a more efficient algorithm.
	* tree-vect-slp.c (vect_slp_analyze_bb_1): Use
	vect_slp_analyze_data_ref_dependences.  Call
	vect_analyze_data_ref_accesses earlier.
	* tree-vect-loop.c (vect_analyze_loop_2): Likewise.
	* tree-vectorizer.h (vect_analyze_data_ref_dependences): Adjust.
	(vect_slp_analyze_data_ref_dependences): New prototype.

	* gcc.dg/vect/vect-outer-3a-big-array.c: Adjust.
	* gcc.dg/vect/vect-outer-3a.c: Likewise.
