New Revision: 115539

URL: http://llvm.org/viewvc/llvm-project?rev=115539&view=rev
Log:
Modified heuristic code to locate local DSNodes in function DSGraphs which are
mirrored in the Globals Graph.  This should help ensure that values DSNodes are 
consistently assigned the same pool regardless of how which DSNode is examined.
