svenpanne@chromium.org 53310ac152 Added a version of the v8::HandleScope constructor with an Isolate and use that consistently.
I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.
