Eli Friedman d2ca493c0b [ARM] Combine ands+lsls to lsls+lsrs for Thumb1. This patch may seem familiar... but my previous patch handled the equivalent lsls+and, not this case. Usually instcombine puts the "and" after the shift, so this case doesn't come up. However, if the shift comes out of a GEP, it won't get canonicalized by instcombine, and DAGCombine doesn't have an equivalent transform. This also modifies isDesirableToCommuteWithShift to suppress DAGCombine transforms which would make the overall code worse. I'm not really happy adding a bunch of code to handle this, but it would probably be tricky to substantially improve the behavior of DAGCombine here.

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.
