94c67375ff [GVNHoist] Some small cleanups 
No functional change is intended, just trying to clean things up a
little.

b636a525d4 code hoisting pass based on GVN 
This pass hoists duplicated computations in the program. The primary goal of
gvn-hoist is to reduce the size of functions before inline heuristics to reduce
the total cost of function inlining.

Pass written by Sebastian Pop, Aditya Kumar, Xiaoyu Hu, and Brian Rzycki.
Important algorithmic contributions by Daniel Berlin under the form of reviews.

ffdaac761a Revert "code hoisting pass based on GVN" 
This reverts commit r274305, since it breaks self-hosting:
  http://lab.llvm.org:8080/green/job/clang-stage1-configure-RA_build/22349/
  http://lab.llvm.org:8011/builders/clang-x86_64-linux-selfhost-modules/builds/17232

Note that the blamelist on lab.llvm.org:8011 is incorrect.  The previous
build was r274299, but somehow r274305 wasn't included in the blamelist:
