Simon Pilgrim 848f45b02f [X86] canonicalizeShuffleWithBinOps - handle general unaryshuffle(binop(x,c)) patterns not just xor(x,-1)
Generalize the shuffle(not(x)) -> not(shuffle(x)) fold to handle any binop with 0/-1.

Hopefully we can further generalize to help push target unary/binary shuffles through binops similar to what we do in DAGCombiner::visitVECTOR_SHUFFLE

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.
