tree-vect-patterns.c (vect_recog_vector_vector_shift_pattern): Properly set vector type of the intermediate stmt. 

2018-06-13  Richard Biener  <rguenther@suse.de>

	* tree-vect-patterns.c (vect_recog_vector_vector_shift_pattern):
	Properly set vector type of the intermediate stmt.
	* tree-vect-stmts.c (vectorizable_operation): The destination
	var always has vectype_out type.
