[AArch64] [-mtune cleanup 3/5] [Temporary] When asked to tune for
Cortex-A57, tune for Cortex-A15
gcc/
* config/aarch64/aarch64-cores.def (cortex-a57): Tune for cortexa15.
* config/aarch64/aarch64-tune.md: Regenerate.
* config/aarch64/aarch64.md: Include cortex-a15 pipeline model.
(generic_sched): "no" if we are tuning for cortexa15.
* config/arm/cortex-a15.md: Include cortex-a15-neon.md by
relative path.
