Log Message:
Updated lang/ocaml to newest version 4.02.2. Changes apart from bugfixes
include:
- #6583: add a new class of binary operators with the same syntactic
  precedence as method calls; these operators start with # followed
  by a non-empty sequence of operator symbols (for instance #+, #!?).
  It is also possible to use '#' as part of these extra symbols
  (for instance ##, or #+#); this is rejected by the type-checker,
  but can be used e.g. by ppx rewriters.

- #6600: make -short-paths faster by building the printing map
  incrementally
