Summary [V8] V8 should be notified of context disposals

We should notify V8 of context disposals to give V8 a chance to cleanup memory from those contexts when idle.

This builds fine on tip of tree Chromium. The V8 version was rolled today with the new interface this is using. Which version of V8 is used for the chromium build here?

The one specified in http://trac.webkit.org/browser/trunk/WebKit/chromium/DEPS (Note that the EWS doesn't understand how to test patches that update this file, but it understands how to update V8 when the file actually changes in SVN.)

Comment on attachment 49721 [details] Notify V8 of context disposals to allow it to clean up when idle. Please put V8GCForContextDispose in its own file (one class per file). Also, please update the DEPS file above so we can keep building upstream. How much power does this idle spin eat? Other than that, looks fine.

> How much power does this idle spin eat? Oops. Never mind. I see that this doesn't spin now.
