Hi all, This patch adds -mcpu/-mtune support for the Arm Neoverse V2 core. This updates the internal references to "demeter", but leaves "demeter" as an accepted value to -mcpu/-mtune as it appears in the released GCC 12 series.
Bootstrapped and tested on aarch64-none-linux-gnu.
Pushing to trunk.
Thanks,
Kyrill
