Instead of using an iterator result object and an entries array (for Map) we introduce a new runtime function that uses an array as an out param. On the Map ForEach perf test this leads to a 2.5x performance improvement. On the overall Map and Set tests this leads to a 18% and 13% improvement respectively.
