Anti-unification is the act of taking two things that do not unify and finding a minimal generalization of them. So for example Vec<u32> anti-unified with Vec<i32> might be Vec<?X>. This is a very simplistic anti-unifier.

Given a current substitution used as guidance for root_goal, and a new possible answer to root_goal, returns a new set of guidance that encompasses both of them. This is often more general than the old guidance. For example, if we had a guidance of ?0 = u32 and the new answer is ?0 = i32, then the guidance would become ?0 = ?X (where ?X is some fresh variable).
