Lattice.LiftConfadds abotandtop, but its argument also required them without using them. Therefore, the sensible thing is to just weaken the argument signature.This allows us to just get rid of
Lattice.LiftPO, which was a copy ofLattice.LiftConfwith basically just this difference (and the handling ofUncomparable).The benefit of this weakening is that fewer dummy
topandbotimplementations are needed just to lift domains without top and bottom. We probably have a bunch around but they're not too easy to find immediately.This is on top of #1727.
