Sanjoy Das c75f995ef0 Teach SCEV normalization to de/normalize non-affine add recs 
Summary:
Before this change, SCEV Normalization would incorrectly normalize
non-affine add recurrences.  To work around this there was (still is)
a check in place to make sure we only tried to normalize affine add
recurrences.

We recently found a bug in aforementioned check to bail out of
normalizing non-affine add recurrences.  However, instead of fixing
the bailout, I have decided to teach SCEV normalization to work
correctly with non-affine add recurrences, making the bailout
unnecessary (I'll remove it in a subsequent change).

I've also added some unit tests (which would have failed before this
change).

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
