Fully fixing bug #3491 (anomaly when building _rect scheme in the
presence of let-ins and recursively non-uniform parameters).
The bug was in the List.chop of Inductiveops.get_arity which was wrong
in the presence of let-ins and recursively non-uniform parameters.
The bug #3491 showed up because, in addition to have let-ins, it was
wrongly detected as having recursively non-uniform parameters.
Also added some comments in declarations.mli.
