* tree-vectorizer.h (vect_get_known_peeling_cost): Adjust
to take a cost vector for scalar iteration cost.
(vect_get_single_scalar_iteration_cost): Likewise.
* tree-vect-loop.c (vect_get_single_scalar_iteration_cost):
Compute the scalar iteration cost into a cost vector.
(vect_get_known_peeling_cost): Use the scalar cost vector to
account for the cost of the peeled iterations.
(vect_estimate_min_profitable_iters): Likewise.
* tree-vect-data-refs.c (vect_peeling_hash_get_lowest_cost):
Likewise.
