Adding "I don't know" as a correct keyword for provers return (inside
counterexamples).
Updating scripts because of move from hoare_logic to WP_revisited.

* src/driver/parse_smtv2_model.ml
(parse): Adding I dont know as a keyword.

* bench/bench
Changing to WP_revisited.

* examples/bench.sh
Changing to WP_revisited.

* examples/regtests.sh
Changing to WP_revisited.

support for 31/32/63/64-bit integers in extracted code

they now live in examples/tests/

also, simplify bench/bench script

- all programs with sessions are in examples/
- all programs without sessions are in examples/in_progress/
  (if you have private sessions for those, just move them there)
- all pure logical problems are in logic/
  (to simplify bench scripts and gallery building; they are few anyway)
- all OCaml programs are in examples/use_api/
- all strange stuff is in examples/misc/
  (most of it should probably go)
- Claude's solutions for Foveoos 2011 are in examples/foveoos11-cm/
  (why do we need two sets of solutions for quite simple problems?)
- hoare_logic, bitvectors, vacid_0_binary_heaps are in examples/

Bench scripts and documentation are updated.
Also, bench/bench is simplified a little bit.
