Stanislav Mekhanoshin c54c76037b Prevent dead uses in register coalescer after rematerialization
The coalescer does not check if register uses are available
at the point of rematerialization. If it attempts to rematerialize
an instruction with such uses it can end up with use without a def.

LiveRangeEdit does such check during rematerialization, so just
call LiveRangeEdit::allUsesAvailableAt() to avoid the problem.

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.
