This patch adds values function to Object that return list of
own values of the object. Patch did according to the point of
spec http://tc39.github.io/ecma262/#sec-object.values

Also patch adds generic builtin intrinsic constants:
@IterationKindKey/@IterationKindValue/@IterationKindKeyValue
that is used in  EnumerableOwnProperties to set Kind of operation
and replace own IterationKind enums in following iterators:
ArrayIterator, MapIterator, and SetIterator
