	* tree-vect-slp.c (vect_free_slp_tree): Also free SLP_TREE_CHILDREN
	vector.
	(vect_create_new_slp_node): Don't allocate node before checking stmt
	type.
	(vect_free_oprnd_info): Remove FREE_DEF_STMTS argument, always
	free def_stmts vectors and additionally free oprnd_info.
	(vect_build_slp_tree): Adjust callers.  Call it even if
	stop_recursion.  If vect_create_new_slp_node or
	vect_build_slp_tree fails, properly handle freeing memory.
	If it succeeded, clear def_stmts in oprnd_info.
