The basic data container for the call graph of a Module of IR.
This class exposes both the interface to the call graph for a module of IR.
The core call graph itself can also be updated to reflect changes to the IR.

| Function * CallGraph::removeFunctionFromModule | ( | CallGraphNode * | CGN | ) |
Unlink the function from this module, returning it.
Because this removes the function from the module, the call graph node is destroyed. This is only valid if the function does not call any other functions (ie, there are no edges in it's CGN). The easiest way to do this is to dropAllReferences before calling this.
