Pete Cooper a18d1734a0 Use RValue refs in APInt add/sub methods. 
This adds versions of operator + and - which are optimized for the LHS/RHS of the
operator being RValue's.  When an RValue is available, we can use its storage space
instead of allocating new space.

On code such as ConstantRange which makes heavy use of APInt's over 64-bits in size,
this results in significant numbers of saved allocations.

Thanks to David Blaikie for all the review and most of the code here.

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