Will this actually ever be needed for other vtables than cxxabi::class_type_info and the others from ItaniumRTTIBuilder::BuildVTablePointer? In what other cases are the vtables referred to from a statically initialized global? And for these vtables - there's no declaration of them at all within most translation units, so that'd require hardcoding all the content of these vtables in ItaniumRTTIBuilder.
