This will probably be a final patch for passing Isolate to V8 APIs that are
called during a DOM object lifetime.

Would you take a look?

LGTM. I'll land this for you.

As discussed offline, it should be possible to make these two functions (and
others that only check predicates) completely inlineable. If these functions are
on a hot path, it might be worth considering that.

Yes, the idea sounds good. I will upload patches in the near future. Thanks!
