It is common for vtables to contain pointers to functions that have either incomplete return types or incomplete argument types.
...
Handle this by returning the llvm::OpaqueType for those cases, which CodeGenModule::GetOrCreateLLVMFunction knows about, and treats as being an "incomplete function".
