Summary: The intent of this is to allow the code to be used with ThinLTO. In Thinlink phase, a traditional Callgraph can not be computed even though all the necessary information (nodes and edges of a call graph) is available. This is due to the fact that CallGraph class is closely tied to the IR. This patch first extends GraphTraits to add a CallGraphTraits graph. This is then used to implement a version of counts propagation on a generic callgraph.
