Fix Coq files after removal of axioms.
Somehow they went under the radar the first time. Now all of them should have been fixed. Strangely enough, as can be seen from the diff, the statement of WP_parameter_gcd was thoroughly wrong. The old proof was actually matching the new statement, so the file would never have compiled on its own. I don't have any sensible explanation for such a breakage, except for gnomes messing with bytes at night.
