Hi all,

This adds support for the Arm Ares CPU in the arm port.
It implements the Armv8.2-A architecture with the relevant optional features
of dot product and FP16 on by default.

Note: Ares is a codename to enable early adopters and in time
we will add the final product name once it's announced.

Tested with check-gas on arm-none-eabi

Ok for master (2.32)?

Thanks,
Kyrill

     * config/tc-arm.c (arm_cpus): Add ares.
     * doc/c-arm.texi (-mcpu): Document ares value.
