Fix Issue #176 so guess_phase() works with genail

- is_phase_known() was returning TRUE
- that's because you need to indicate that there's a phase-known version
  of the cross type in the cross_*.h file.
- technically, we need to create a genailpk cross type. I think this is
  only used in est_map().
