[binutils][aarch64] Matrix Multiply extension enablement [8/X]

Browse Source 
Hi,

This patch is part of a series that adds support for Armv8.6-A
(Matrix Multiply and BFloat16 extensions) to binutils.

This patch introduces the Matrix Multiply (Int8, F32, F64) extensions
to the aarch64 backend.

The following instructions are added: {s/u}mmla, usmmla, {us/su}dot,
fmmla, ld1rob, ld1roh, d1row, ld1rod, uzip{1/2}, trn{1/2}.

Committed on behalf of Mihail Ionescu.

Regression tested on arm-none-eabi.

Is it ok for trunk?
