Evandro Menezes 21f9ce1a0d [DAG Combiner] Fix the native computation of the Newton series for reciprocals ...

The generic infrastructure to compute the Newton series for reciprocal and
reciprocal square root was conceived to allow a target to compute the series
itself.  However, the original code did not properly consider this condition
if returned by a target.  This patch addresses the issues to allow a target
to compute the series on its own.
