This patch adds AArch32 support for -march=armv9.[123]-a.
The behaviour of the new options can be expressed using a
combination of existing feature flags and tables.
The cpu_arch_ver entries for ARM_ARCH_V9_2A and ARM_ARCH_V9_3A
are technically redundant but it seemed less surprising to include
them anyway.
Tested on arm-linux-gnueabi and arm-eabi. OK to install?
Richard
