[AArch64][Patch 4/5] Support HINT aliases taking operands.

Browse source 
The Statistical Profile Extension adds the instruction PSB CSYNC as an
alias for the HINT #17 instruction. This patch adds support for aliases
of HINT which take an operand, adding a table to store operand names and
their matching hint number as well as encoding and decoding functions
for such operands. Parsing and printing the operands are deferred to any
support added for aliases with such operands.
