Aliaksandr Kalenik f405d71657 LibJS: Disable optimization in IteratorNextUnpack if next() is redefined 
81b6a11 regressed correctness by always bypassing the `next()` method
resolution for built-in iterators, causing incorrect behavior when
`next()` was redefined on built-in prototypes. This change fixes the
issue by storing a flag on built-in prototypes indicating whether
`next()` has ever been redefined.
