the reference to SourceUnit is hold by he abstract method
getSourceUnit(), which every subclass of that visitor has to implement.
Moving getSourceUnit and addError up into CodeVisitorSupport means to
possibly break existing code because getSourceUnit is abstract and
addError requires the SourceUnit.
