[AArch64, 2/6] Add new arch command line feaures from ARMv8.5-A
This patch is part of a series that enables ARMv8.5-A in GCC and
adds Branch Target Identification Mechanism.
This patch add all the command line feature that are added by ARMv8.5.
Optional extensions to armv8.5-a:
+rng : Random number Generation Instructions.
+memtag : Memory Tagging Extension.
ARMv8.5-A features that are optional to older arch:
+sb : Speculation barrier instruction.
+ssbs: Speculative Store Bypass Safe instruction.
+predres: Execution and Data Prediction Restriction instructions.
All of the above only effect the assembler and have already gone in the
trunk of binutils.
