GInterfaceInfo.Data was automatically set to be a GCHandle on the interface adapter. But the generated GInterfaceInitHandlers were not using it, just free'ing it. But for the GInterface property support, the Data field is now used to pass the class pointer, so casting it to a GCHandle to free it would cause an exception. We now don't assume anything about GInterfaceInfo.Data.
