This patch adds support for Arm's Cortex-R82 CPU to GCC. For more
information about this CPU, see [0].
Testing:
* Bootstrapped and regtested on aarch64-none-linux-gnu, no regressions.
[0] : https://developer.arm.com/ip-products/processors/cortex-r/cortex-r82
OK for trunk?

gcc/ChangeLog:
* config/aarch64/aarch64-cores.def: Add Cortex-R82.
* config/aarch64/aarch64-tune.md: Regenerate.
* doc/invoke.texi: Add entry for Cortex-R82.
