Craig Topper cad0669c4c [InstCombine] Don't transform ((C1 OP zext(X)) & C2) -> zext((C1 OP X) & C2) if either zext or OP has another use.

If they have other users we'll just end up increasing the instruction count.

We might be able to weaken this to only one of them having a single use if we can prove that the and will be removed.

Fixes PR41164.

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.
