tree-vectorizer.h (struct _slp_oprnd_info): Add second_pattern member. 

2015-05-22  Richard Biener  <rguenther@suse.de>

	* tree-vectorizer.h (struct _slp_oprnd_info): Add second_pattern
	member.
	* tree-vect-loop.c (vect_analyze_loop_operations): Look at
	patterns when determining whether SLP is pure.
	(vect_is_slp_reduction): Remove check for pattern stmts.
	(vect_is_simple_reduction_1): Remove dead code.
	* tree-vect-slp.c (vect_create_oprnd_info): Initialize second_pattern.
	(vect_get_and_check_slp_defs): Pass in the stmt number.
	Allow the first def in a reduction to be not a pattern stmt when
	the rest of the stmts def are patterns.
	(vect_build_slp_tree_1): Allow tcc_expression codes like
	SAD_EXPR and DOT_PROD_EXPR.
	(vect_build_slp_tree): Adjust.
	(vect_analyze_slp): Refactor and move BB vect error message ...
	(vect_slp_analyze_bb_1): ... here.
