Nikita Popov 50ac6afd84 [InstCombine] Fix worklist management in return combine
There are two related bugs here: First, we don't add the operand
we're replacing to the worklist, which means it may not get DCEd
(see test change). Second, usually this would just get picked up
in the next iteration, but we also do not report the instruction
as changed. This means that we do not get that extra instcombine
iteration, and more importantly, may break the pass pipeline, as
the function is not marked as changed.

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.
