vect: Refactor peel_iters_{pro,epi}logue cost modeling
This patch is to refactor the existing peel_iters_prologue and
peel_iters_epilogue cost model handlings, by following the structure
below suggested by Richard Sandiford:
- calculate peel_iters_prologue
- calculate peel_iters_epilogue
- add costs associated with peel_iters_prologue
- add costs associated with peel_iters_epilogue
- add costs related to branch taken/not_taken.
Bootstrapped/regtested on aarch64-linux-gnu.
gcc/ChangeLog:
* tree-vect-loop.c (vect_get_known_peeling_cost): Factor out some code
to determine peel_iters_epilogue to...
(vect_get_peel_iters_epilogue): ...this new function.
(vect_estimate_min_profitable_iters): Refactor cost calculation on
peel_iters_prologue and peel_iters_epilogue.
