New Revision: 56144

URL: http://llvm.org/viewvc/llvm-project?rev=56144&view=rev
Log:
Give GlobalsModRef a whirl in the nightly testers.
I placed it just before GVN because that it is the
pass most likely to benefit from it.  Some quick
and dirty testing confirms that this is a decent
place for it.
