Could you further explain how to "hide" RunEarly under an EarlyExternalAA and LateExternalAA wrapper class?

Do you mean making the constructor of ExternalAAWrapperPass to be 
```
explicit ExternalAAWrapperPass(CallbackT CB, bool RunEarly = false);
```
and having 
```
  NVPTXExternalAAWrapper()
      : ExternalAAWrapperPass([](Pass &P, Function &, AAResults &AAR) {
          if (auto *WrapperPass =
                  P.getAnalysisIfAvailable<NVPTXAAWrapperPass>())
            AAR.addAAResult(WrapperPass->getResult());
        }, /*RunEarly=*/true) {}
```
?
