- Add JSReceiver::SetIntegrityLevel, with a fast path for regular objects.
- Make Object.{freeze,seal} call this via %Object{Freeze,Seal}, thus no longer
using broken or deprecated functions from v8natives.js.
- Add JSReceiver::OwnPropertyKeys convenience function.
- Reenable harmony/proxies-hash.js test.
