This rolls back V8 to the version we had previously. I had originally rolled this forward to match what Chrome was using (r3030 of v8), but using that version of v8 stops us from rendering for some reason.  I'm rolling this back so we can render again, but we'll have to figure out what broke our rendering before we can roll v8 forward. Review URL: http://codereview.chromium.org/271039
