AArch64: backport Neoverse and Cortex CPU definitions
This is a conservative backport of a few core definitions backporting only
the
core definitions and mapping them to their closest cost model that exist on
the
branches.
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (cortex-a725, cortex-x925,
neoverse-n3, neoverse-v3, neoverse-v3ae): New.
* config/aarch64/aarch64-tune.md: Regenerate
* doc/invoke.texi: Document them.
