[AArch64, Binutils] Add missing TSB instruction
This patch implements the TSB instructions:
https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/
tsb-csync-trace-synchronization-barrier
Since TSB and PSB both use the same (and only) argument "CSYNC", this patch
reuses it for TSB. However, the same argument would imply different value
for CRm:Op2 which are anyway fixed values, so I have diverted the
inserter/extracter function to dummy versions instead of the "hint" version.
The operand checker part still uses the existing infratructure for
AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly.
gas/ChangeLog:
