LGTM with a nit

https://codereview.chromium.org/15964004/diff/1/test/cctest/test-debug.cc
File test/cctest/test-debug.cc (right):

https://codereview.chromium.org/15964004/diff/1/test/cctest/test-debug.cc#new...
test/cctest/test-debug.cc:6623: v8::Local<v8::Context> local_context =
v8::Context::New(isolate);
Can't we use Context::Scope here? BTW: It would be good to balance the
parentheses in Context::Scope again. Not from this CL, but anyway...
