Previously, Object.values() and Object.entries() were piggy-backing on Object.keys(). This meant that they would pre-filter non-enumerable properties, violating the runtime behaviour of the methods. Unfortunately, this does not match the current proposal text. Also incorporates several tests verifying this behaviour based on tests included in the ChakraCore implementation. In this reland, the new patch fills up the longer-lasting FixedArray with `undefined` to avoid the crash in Heap::Verify().
