        Added some helper functions which provide strings to display in the
        Xcode debugger's variable inspector window. These functions are called
        from the LabyrinthDataFormatter debugger plugin I just checked in to
        the Labyrinth/Tools directory.

        Note that these functions are compiled in on Development builds only.

        * WebCore-combined.exp:
        * WebCore-tests.exp: Export all the formatForDebugger symbols so the
        debugger program can link with them.

        (DOM::RangeImpl::formatForDebugger):
