Benedikt Meurer 3b84cbfeb0 [builtins] Port Map and Set iterators to CodeStubAssembler. ... This is the next step towards faster Map and Set iteration. It introduces the appropriate instance types for Map and Set iterators (following the pattern for Array iterators) and migrates the following builtins to the CodeStubAssembler: - Set.prototype.entries - Set.prototype.values - Map.prototype.entries - Map.prototype.keys - Map.prototype.values - %SetIteratorPrototype%.next - %MapIteratorPrototype%.next This already provides a significant performance boost for regular for-of iteration of Sets and Maps, by a factor of 5-10 depending on the input. The final step will be to inline some fast-paths into TurboFan. Drive-by-fix: Remove obsolete %IsJSSetIterator and %IsJSMapIterator intrinsics and runtime functions.
