       \brief Return the nonzero subresultants of \c p and \c q with respect to the "variable" \c x.

       \pre \c p, \c q and \c x are Z3 expressions where \c p and \c q are arithmetic terms.
       Note that, any subterm that cannot be viewed as a polynomial is assumed to be a variable.
       Example: \ccode{f(a)} is a considered to be a variable in the polynomial \ccode{
       f(a)*f(a) + 2*f(a) + 1}
