  M t/pmc/class.t

Log Message:
-----------
Remove the restriction in Class.add_vtable_override against adding an override that has already been added. This is the kind of semantic HLLs should enforce, not Parrot (especially since we won't do any caching, so we don't have to worry about inconsistency).
