Instead of using plain objects as Iterator records, causes confusion about the object itself actually being its [[Iterator]] slot, and requires non-standard type conversion shenanigans fpr the [[NextValue]] and [[Done]] internal slots, implement a proper Iterator record struct and use it throughout. Also annotate the remaining Iterator AOs with spec comments while we're here.
