Printtyp: avoid stack overflow when printing constructors or records
Toplevel functions exported by the Printtyp should in general prepare
all types involved in the printing.
The toplevel `constructor`, `label` and `extension_only_constructor`
functions didn't prepare their arguments and return types
making the printer loops on such types.
