[Patch 00/16] [gas][aarch64] SVE2 binutils instructions for aarch64

[Matthew Malcomson]

This series of patches adds support for the "Future Architecture Technologies"
Scalable Vector Extension V2 (SVE2) announced at Linaro Connect.
https://connect.linaro.org/resources/bkk19/new-technologies-in-the-arm-architecture/

Tested by comparing against an independent implementation with the testfile
provided and running the testsuite on an aarch64-linux-gnu cross-assembler.

The instructions and testcases are added in the final two patches to keep the
number of patches that need to be zipped to a minimum.

The instructions are published at the link below.
