    Fix treatment of rest pattern in array destructuring. · 4edf16dd
    neis authored
    When seeing a rest pattern, we used to get the remaining elements from the
    iterator by calling %concat_iterable_to_array on it.  This was wrong because it
    caused an observable [[Get]] for @@iterator (which the iterator may not even
    provide).
    
    This CL gets rid of the call to %concat_iterable_to_array and does the iteration
    manually in a simple while-loop.  It also gets rid of %concat_iterable_to_array
    itself because there aren't any other uses of it.
