Craig Topper 4e78213ae4 [X86] Move the memory unfolding table creation into its own class and make it a ManagedStatic.
Also move the static folding tables, their search functions and the new class into new cpp/h files.

The unfolding table is effectively static data. It's just a different ordering and a subset of the static folding tables.

By putting it in a separate ManagedStatic we ensure we only have one copy instead of one per X86InstrInfo object. This way also makes it only get initialized when really needed.

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
