tree-vect-stmts.c (vectorizable_load): Initialize slp_perm earlier and remove ??? comment. 

2015-05-27  Richard Biener  <rguenther@suse.de>

	* tree-vect-stmts.c (vectorizable_load): Initialize slp_perm
	earlier and remove ??? comment.
	(vect_analyze_stmt): If we are analyzing a pure SLP stmt
	and got called from loop analysis bail out.  Always pass the SLP
	node to the vectorizable_* functions.
	* tree-vect-loop.c (vect_analyze_loop_operations): Remove
	the premature SLP check here.
	* tree-vect-slp.c (vect_detect_hybrid_slp_stmts): Dump hybrid
	detected SLP stmts.
	(vect_detect_hybrid_slp_1): Likewise.
