UOrdering2 and UOrdering3 are emitted by SMTLibLineariser for VCExprSubtypeOp and VCExprSubtype3Op. Those appear only as members of the SingletonOp enum: there is no VCExprOp for either, no generator builds one, and SingletonOpDict maps neither -- so no node can carry them and neither symbol can be applied. Boogie declared both in the background predicates regardless, which put them in every polymorphic-encoding model; a pruning golden shrinks accordingly. The lineariser's visitors are left alone, being reachable only if the ops are ever built.
