The call to GetValueAsUnsigned included a boolean, 'success' which would be set correctly if the call fails, and which I was checking upon return. But, if I use Greg's code from above then I omit the call to GetValueAsUnsigned, anyway.  And yes, I am converting these GetValueAs... functions to return an llvm::Expected<> value.
