[AArch64][Patch 5/5] Add instruction PSB CSYNC
The Statistical Profile Extension adds the instruction PSB CSYNC as an
alias for the HINT #17 instruction. This patch adds the instruction to
binutils as a HINT alias that takes an operand.
A new operand type, AARCH64_OPND_BARRIER_PSB, is added to represent the
operand to PSB. A parser for the operand type is added to the assembler
and a printer to the disassembler. The operand name "csync" is added to
the list of HINT options with HINT number #17. Encoding and decoding of
the operand is handled by the ins_hint/ext_hint functions added in the
preceding patches.
