J. Ryan Stinnett 7a1d5ef703 [DebugInfo][NFC] Add instr-ref documentation, migration guide
This used to be D102158, but all the code it describes got re-written, so I
figured I'd take another shot at documenting the new instruction referencing
variable locations, this time from a higher level. Happily there's no longer any
need to describe LiveDebugValues in any detail seeing how it's all SSA-based
now.

Probably the most important part is the explanation of what targets need to do
to support instruction referencing. The list is small, mostly because there's
nothing especially complicated that targets need to do: just instrument their
target-specific optimisations and implement the stack spill/restore recognition
target hooks.

This is a small amount of text (which is a virtue), I'm extremely happy to
expand on anything.

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.
