Subject: Monomorphized a lot of equalities over OCaml integers, thanks to the
 new Int module. Only the most obvious were removed, so there are a lot more
 in the wild.

This may sound heavyweight, but it has two advantages:

1. Monomorphization is explicit, hence we do not miss particular
optimizations of equality when doing it carelessly with the generic
equality.

2. When we have removed all the generic equalities on integers, we
will be able to write something like "let (=) = ()" to retrieve all
its other uses (mostly faulty) spread throughout the code, statically.
