David Green a25701e711 [ARM] Match MVE vqdmulh 
This adds ISel matching for a form of VQDMULH. There are several ir
patterns that we could match to that instruction, this one is for:

min(ashr(mul(sext(a), sext(b)), 7), 127)

Which is what llvm will optimize to once it has removed the max that
usually makes up the min/max saturate pattern, as in this case the
compare will always be false. The additional complication to match i32
patterns (which extend into an i64) is that the min will be a
vselect/setcc, as vmin is not supported for i64 vectors. Tablegen
patterns have also been updated to attempt to reuse the MVE_TwoOpPattern
patterns.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
