Idan Horowitz 2a3090d292 LibJS: Add the SetIterator built-in and Set.prototype.{values, entries}
While this implementation should be complete it is based on HashTable's
iterator, which currently follows bucket-order instead of the required
insertion order. This can be simply fixed by replacing the underlying
HashTable member in Set with an enhanced one that maintains a linked
list in insertion order.
