This is needed for the ABSU_EXPR changes. It fixes a latent issue
in vect_recog_vector_vector_shift_pattern as well.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

* 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.
