Diogo N. Sampaio 9c9067316b [NFC][AArch64] Split out backend features
This patch splits backend features currently
hidden behind architecture versions.

For example, currently the only way to activate
complex numbers extension is targeting an v8.3
architecture, where after the patch this extension
can be added separately.

This refactoring is required by the new command lines proposal:

It was reverted in rL348249 due a	build bot failure in one of the
regression tests:
http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win/builds/14386

The problem seems to be that FileCheck behaves
different in windows and linux. This new patch
splits the test file in multiple,
and does more exact pattern matching attempting
to circumvent the issue.

This has been causing buildbots failures for the past 24 hours: http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win/builds/14386

Oliver Stannard 64c167db7a [AArch64] Add ARMv8.2-A new AT instruction variants
ARMv8.2-A adds new variants of the "at" (address translate) system
instruction, which take the PSTATE.PAN bit (added in ARMv8.1-A). These
are a required part of ARMv8.2-A, so no additional subtarget features
are required.
