Jessica Paquette 8e321c8c5a [GlobalISel] Combine (logic_op (op x...), (op y...)) -> (op (logic_op x, y)) 
This implements

```
(logic_op (op x...), (op y...)) -> (op (logic_op x, y))
```

when `op` is an extend, a shift, or an and.

This is similar to `DAGCombiner::hoistLogicOpWithSameOpcodeHands`
(with a bunch of missing cases, e.g. G_TRUNC, G_BITCAST, etc.)

This is implemented so it works both pre and post-legalization.

This also adds a general way to add a series of instructions in a combine.
(`applyBuildInstructionSteps`).

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.
