vect: Pass scalar_costs to finish_cost
When finishing the vector costs, it can be useful to know
what the associated scalar costs were. This allows targets
to read information collected about the original scalar loop
when trying to make a final judgement about the cost of the
vector code.
This patch therefore passes the scalar costs to
vector_costs::finish_cost. The parameter is null for the
scalar costs themselves.
gcc/
* tree-vectorizer.h (vector_costs::finish_cost): Take the
corresponding scalar costs as a parameter.
(finish_cost): Likewise.
* tree-vect-loop.c (vect_compute_single_scalar_iteration_cost)
(vect_estimate_min_profitable_iters): Update accordingly.
* tree-vect-slp.c (vect_bb_vectorization_profitable_p): Likewise.
* tree-vectorizer.c (vector_costs::finish_cost): Likewise.
* config/aarch64/aarch64.c (aarch64_vector_costs::finish_cost):
Likewise.
* config/rs6000/rs6000.c (rs6000_cost_data::finish_cost): Likewise.
