vect: Remove vec_outside/inside_cost fields
The vector costs now use a common base class instead of being
completely abstract. This means that there's no longer a
need to record the inside and outside costs separately.
gcc/
* tree-vectorizer.h (_loop_vec_info): Remove vec_outside_cost
and vec_inside_cost.
(vector_costs::outside_cost): New function.
* tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Update
after above.
(vect_estimate_min_profitable_iters): Likewise.
(vect_better_loop_vinfo_p): Get the inside and outside costs
from the loop_vec_infos' vector_costs.
