3657d4c3ab feat(frontends/lean): coercion num -> int even when nat is not open, closes #219
I also had to mark the coercions as reducible.
Otherwise, given the constraint

          ?M (int.of_num 0) =?= (int.of_nat (nat.to_nat 0))

the unifier will not generate the solution

          ?M := fun x, x

3ca1264f61 refactor(library): mark 'decidable' theorems as definitions
If we don't do that, then any 'if' term that uses one of these theorems
will get "stuck". That is, the kernel will not be able to reduce them
because theorems are always opaque
