Shuxin Yang a0c9939873 Perform factorization as a last resort of unsafe fadd/fsub simplification.
Rules include:
  1)1 x*y +/- x*z => x*(y +/- z) 
    (the order of operands dosen't matter)

  2) y/x +/- z/x => (y +/- z)/x 

 The transformation is disabled if the new add/sub expr "y +/- z" is a 
denormal/naz/inifinity.

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

This directory and its subdirectories contain source code for the Low Level
Virtual Machine, 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
