#9389: Bug in polynomials over residue fields (was: sage crashing when computing
local_data() for an EC)

Comment(by ylchapuy):
polynomial_zz_pex should not be used here.
{{{
is_FiniteField(base_ring):
}}}
might be the wrong test because
{{{
sage: K.ideal(2).residue_field().is_finite()
yes
}}}
We should change the line
{{{
if implementation == "NTL" and is_FiniteField(base_ring):
}}}
to something appropriate, it should only be used for
`PolynomialRing(GF(q))` I guess
