pushing skolems under 'iff' sometimes breaks things further down the proof (as was to be feared)

If the code generation ends with an exception with the following message:
'"List.set" is not a constructor, on left hand side of equation: ...',
the code equation in question has to be either deleted (like many others in this file)
or implemented for RBT trees.
