Missing serialize REPR function for REPR VMHash
(Rakudo​::Internals​::IterationSet)

From @lizmat

Confirmed.

Apparently we need to teach something that Rakudo​::Internals​::IterationSet is nothing but an nqp​::hash.

Or we need to revert the 5% performance gains on creating sets and set operators that having Rakudo​::Internals​::IterationSet brought.
