Owen Anderson bc227b65c2 Change a very hot piece of code in TableGen's register unit computations to use bit vectors rather than arrays. 
For target descriptions with very large and very dense register files, TableGen
can take an extremely long time to run.  This change makes a dent in that (~15%
in my measurements) by accelerating the single hottest operation with better data
structures.

I believe there's still a lot of room to make this even faster with more global
changes that require replacing some of the existing datastructures in this area
with bit vectors, but that's a more involved change and I wanted to get this
simpler improvement in first.

Low Level Virtual Machine (LLVM)
================================

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're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
