Sanjay Patel 571ed3a774 [InstCombine] improve matching for sext-lshr-trunc patterns, part 2 
Similar to rG42f488b63a04

This is intended to preserve the logic of the existing transform,
but remove unnecessary restrictions on uses and types.

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.
