Simon Pilgrim 3079e51858 [X86][SSE] Generalize shuffle(HORIZOP,HORIZOP) -> HORIZOP combine
Our existing combine allows to merge the shuffle of 2 similar 64-bit wide 'horizontal ops' (HADD/PACK/etc.) if the shuffle was a UNPCK/MOVSD.

This patch generalizes this to decode any target shuffle mask that can be widened to a 128-bit repeating v2*64 mask, which helps us catch PBLENDW/PBLENDD cases.

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.
