[PATCH 0/7][Binutils] aarch64: Fix the FEAT_SVE2p1 related issues.

[srinath]

Hi,

The FEAT_SVE2p1 related issues were reported here [1] and I have posted
few patches to fix those issues [2].

This patch series is the re-spin of those patches in [2], splitting them and
also addresssing other issues like adding extra tests for FEAT_SVE2p1
instructions and fix FEAT_B16B16 sve2 instruction constraints.
