I think the Instantiate* methods should all return consistent error codes, so I'd like to keep this. I can do `return !Instantiation->getInClassInitializer()`, though, since that is the error case.
Should I be marking the Instantiation FieldDecl invalid if instantiation fails? Otherwise the next time we hit a constructor I think we'll try to reinstantiate. I'll handle this in a followup commit if you think this is better.
