Removes debug flag: debug_auto_model.
Some changes in counterexamples triggered by:
- (non counterexamples) transformations which have a specific case for
   model_trace but not for the new detection: this is intended as
   simplifications that would be done are often simplifications we want
   for counterexamples,
- Some locations are missing in variables introduced by SP/WP which should
  explain the rest.

This also disables projections for record in intro_projection_counterexmp.

Correct subst_filter to be consistent with new counterexample modification

rename_file: change behavior and properly remove ide related stuff.

Remove unused attributes.

This is still not ideal, because we may miss cases where
a proxy variable is used before being defined:

  forall o_proxy, r. r = o_proxy -> o_proxy = 2 -> r + r = 5

However, I am not sure this really happens in practice.

This commit also raises an assertion failure on Ehole and Eany in the
OCaml printer. (This was already the case for the C printer.)

Mark "any" expressions as ghost. (Fix #225.)

Closes #225

See merge request !53

This breaks extraction of multiprecision/wmpn.mlw.

Need some code refactoring, especially to avoid some (likely) unecessary module
translations.
