Sudakshina Das 503ba60025 [BINUTILS, AARCH64, 6/8] Add Tag getting instruction in Memory Tagging Extension
This patch is part of the patch series to add support for ARMv8.5-A
Memory Tagging Extensions which is an optional extension to
ARMv8.5-A and is enabled using the +memtag command line option.

This patch add support to the Bulk Allocation Tag instructions from
MTE. These are the following instructions added in this patch:
- LDGV <Xt>, [<Xn|SP>]!
- STGV <Xt>, [<Xn|SP>]!

This needed a new kind of operand for the new addressing [<Xn|SP>]!
since this has no offset and only takes a pre-indexed version.
Hence AARCH64_OPND_ADDR_SIMPLE_2 and ldtdgv_indexed are introduced.
(AARCH64_OPND_ADDR_SIMPLE fulfilled the no offset criteria but does
not allow writeback). We also needed new encoding and decoding
functions to be able to do the same.

where
<Xt> : Is the 64-bit destination GPR.
<Xn|SP> : Is the 64-bit first source GPR or Stack pointer.
