Subject: 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.
