With the GC heap conversion, the functionality of legacy platform objects was broken. This is because the generated implementation of one of them was used for all of them, removing functionality such as deletion. This re-adds all functionality, where questions such as "does the object support indexed properties?" is instead answered by virtual functions instead of by the IDL generator checking the presence of certain keywords/attributes.
