[AArch64, Binutils] Make hint space instructions valid for Armv8-a
There are a few instruction in AArch64 that are in the HINT space. Any of
these instructions should be accepted by the assembler/disassembler at any
architecture version. This patch fixes the existing instructions that are
not behaving accordingly.
I have used all of the instructions mentioned in the following to make the
changes:
