Builds a call graph by first collecting all call graph edges before the final
CallGraph is created.
This class is not thread-safe.
This class is used internally by the methods of the CallGraphFactory to build
the call graph. That class/those methods takes care of all thread-safety issues.
Adds the given callEdges to the call graph.
If callEdges contains another edge for a previously added (Method,PC) pair
then this edge will be added to the potential targets for the respective
invoke instruction (referred to by the (Method,PC) pair).
Builds the final call graph.
