tree-vectorizer.h (vect_slp_analyze_data_ref_dependences): Rename to vect_slp_analyze_instance_dependence.

2015-11-12  Richard Biener  <rguenther@suse.de>

	* tree-vectorizer.h (vect_slp_analyze_data_ref_dependences):
	Rename to vect_slp_analyze_instance_dependence.
	* tree-vect-data-refs.c (vect_slp_analyze_data_ref_dependence):
	Remove WAR special-case.
	(vect_slp_analyze_node_dependences): Instead add more specific
	code here, not relying on other instances being vectorized.
	(vect_slp_analyze_instance_dependence): Adjust accordingly.
	* tree-vect-slp.c (vect_build_slp_tree_1): Remove excessive
	vertical space in dump files.
	(vect_print_slp_tree): Likewise.
	(vect_analyze_slp_instance): Dump a header for the final SLP tree.
	(vect_slp_analyze_bb_1): Delay computing relevant stmts and
	not vectorized stmts until after dependence analysis removed
	instances.  Merge alignment and dependence checks.
	* tree-vectorizer.c (pass_slp_vectorize::execute): Clear visited
	flag on all stmts.
