This could be more efficient depending on how well a given compiler does RVO.

The proposed changes:

[ ] fix a bug or incorrect behavior in AMReX
[ ] add new capabilities to AMReX
[ ] changes answers in the test suite to more than roundoff level
[ ] are likely to significantly affect the results of downstream AMReX users
[ ] include documentation in the code and/or rst files, if appropriate
