simplify_function() mustn't try to evaluate functions that return
composite types, because TupleTableSlots aren't Datums and can't be
stored in Const nodes.  We can remove this restriction if we ever
adopt a cleaner runtime representation for whole-tuple results, but
at the moment it's broken.  Per example from Thomas Hallgren.
