Jeremy Morse ee50590e16 [DebugInfo] MachineSink: Insert undef DBG_VALUEs when sinking instructions
When we sink DBG_VALUEs between blocks, we simply move the DBG_VALUE
instruction to below the sunk instruction. However, we should also mark
the variable as being undef at the original location, to terminate any
earlier variable location. This patch does that -- plus, if the
instruction being sunk is a copy, it attempts to propagate the copy
through the DBG_VALUE, replacing the destination with the source.

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.

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.
