[PATCH] aarch64: Add -march support for Armv9.1-A, Armv9.2-A, Armv9.3-A

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This is a straightforward patch that allows targeting the architecture 
revisions mentioned in the subject
through -march. These are already supported in binutils.

Bootstrapped and tested on aarch64-none-linux-gnu.
Pushing to trunk.
Thanks,
Kyrill
