aarch64: Add command-line support for Armv8.8-a
This final patch in the series is much simpler and adds command-line support for -march=armv8.8-a,
making use of the +mops features added in the previous patches.
Bootstrapped and tested on aarch64-none-linux-gnu.
gcc/ChangeLog:
* config/aarch64/aarch64-arches.def (armv8.8-a): Define.
* config/aarch64/aarch64.h (AARCH64_FL_V8_8): Define.
(AARCH64_FL_FOR_ARCH8_8): Define.
* doc/invoke.texi: Document -march=armv8.8-a.
