softfloat: Fix division
The __udiv_qrnnd primitive that we nicked from gmp requires its
inputs to be normalized. We were not doing that. Because the
inputs are nearly normalized already, finishing that is trivial.
Replace div128to64 with a "proper" udiv_qrnnd, so that this
remains a reusable primitive.
