Implement interface for NoAlias assignments.

* Rename the old copy_using_evaluators to noalias_copy_using_evaluators.
* Write a new copy_using_evaluators which strips NoAlias expression, if present,
and calls noalias_copy_using_evaluators; in future, it will also take care of
aliasing in products.
* Add expression() getter to NoAlias.
