Another question - do you think we could replace forward references by the the concrete ones?
ie.replace references to 0x100E with 0x1016, and remove 0x100E:

  CHECK:   0x100E | LF_STRUCTURE [size = 108, unreferenced] `__vc_attributes::event_sourceAttribute`
  CHECK:            unique name: `.?AUevent_sourceAttribute at __vc_attributes@@`
  CHECK:            vtable: <no type>, base list: <no type>, field list: <no type>
  CHECK:            options: forward ref (-> 0x1016) | has unique name, sizeof 0

  CHECK:   0x1016 | LF_STRUCTURE [size = 108, unreferenced] `__vc_attributes::event_sourceAttribute`
  CHECK:            unique name: `.?AUevent_sourceAttribute at __vc_attributes@@`
  CHECK:            vtable: <no type>, base list: <no type>, field list: 0x1015
  CHECK:            options: has ctor / dtor | contains nested class | has unique name, sizeof 12
