This does not add support for these version (and the corresponding
__ARM_FEATURE_<X> macros aren't implemented for this reason) but
accepts the command line strings and allows these to be passed on to
the assembler.
Armv9.6-A is supported by the new "armv9.6-a" option and defined as
"armv9.5-a+cmpbr+lsui+occmo"
The new extensions are:
- fprcvt (FEAT_FPRCVT)
- lsfe (FEAT_LSFE)
- f8f32mm (FEAT_F8F32MM)
- f8f16mm (FEAT_F8F16MM)
- sme2p2 (FEAT_SME2p2)
- sve2p2 (FEAT_SVE2p2)
- sve-aes2 (FEAT_SVE_AES2)
- sve-f16f32mm (FEAT_SVE_F16F32MM)
- sve-bfscale (FEAT_SVE_BFSCALE)
- ssve-aes (FEAT_SSVE_AES)
- lsui (FEAT_LSUI)
- occmo (FEAT_OCCMO)
- pcdphint (FEAT_PCDPHINT)
- pops (FEAT_PoPS)
- ssve-bitperm (FEAT_SSVE_BitPerm)
- ssve-fexpa (FEAT_SSVE_FEXPA)
- sme-mop4 (FEAT_SME_MOP4)
- sme-tmop (FEAT_TMOP)
