Hi All,

This patch is a respin of the previous one defining a new helper
function add_pattern_stmt.

Ok for master?

Thanks,
Tamar

	* tree-vect-patterns.c (vect_mark_pattern_stmts): Remove static inline.
	* tree-vect-slp.c (vect_create_new_slp_node): Remove static and only
	set smts if valid.
	* tree-vectorizer.c (vec_info::add_pattern_stmt): New.
