Constraints for type inference

When doing conversion of universes, not only do we have =/<= constraints but also Lub constraints which correspond to unification of two levels which might not be necessary if unfolding is performed.

UWeak constraints come from irrelevant universes in cumulative polymorphism.

Sourcetype t =
  1. | ULe of Sorts.t * Sorts.t
  2. | UEq of Sorts.t * Sorts.t
  3. | ULub of Univ.Level.t * Univ.Level.t
  4. | UWeak of Univ.Level.t * Univ.Level.t
Sourceval is_trivial : t -> bool
Sourceval check : UGraph.t -> t -> bool
Sourceval check_eq_level : UGraph.t -> Univ.Level.t -> Univ.Level.t -> bool

Wrapper around the UGraph function to handle Prop
