Probably the best way to construct a CFG is to have an AnalysisContext object do it for you.  You can construct an AnalysisContext object using a FunctionDecl, and then call the getCFG() method to have it lazily create a CFG.  When the AnalysisContext object is destroyed, the CFG will be destroyed as well.
