Sanjoy Das e4f44dfa73 Make SCEVRewriteVisitor smarter about when it trys to create SCEVs 
This change really saves just one foldingset lookup, but makes
SCEVRewriteVisitor "feature compatible" with the handwritten logic in
ScalarEvolutionNormalization, so that I can change
ScalarEvolutionNormalization to use SCEVRewriteVisitor in a next step.

This is a non-functional change, but _may_ improve performance in some
pathological cases, but that's unlikely.

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.
