Declare that the domain of the type ty_id is restricted to given list of cases, in the form forall var. Or_{c in cases} var = c. The type of var must be ty_id ty_vars. Will be ignored if the type already has a enum declaration, and the old declaration will be returned instead.
Raises Error if some of the preconditions is not filled
Returns either the new declaration, or the already existing one for this type if any
