Strange/broken serialization of min_int

[hcarty]

OCaml 4.02.3 on 64bit Linux, yojson 1.2.1 installed with opam

utop # Yojson.Safe.to_string @@ `Int min_int
- : string = "-,*//*(*0/(,.)-()'0,"
utop # Yojson.Safe.to_string @@ `Int (min_int + 1)
- : string = "-4611686018427387903"
utop # Yojson.Safe.to_string @@ `Int max_int
- : string = "4611686018427387903"
