new solver cleanup + implement coherence the cleanup: - change `Certainty::unify_and` to consider ambig + overflow to be ambig - rename `trait_candidate_should_be_dropped_in_favor_of` to `candidate_should_be_dropped_in_favor_of` - remove outdated fixme For coherence I mostly just add an ambiguous candidate if the current trait ref is unknowable. I am doing the same for reservation impl where I also just add an ambiguous candidate.
