Get CJS_RuntimeFactory out of the CJS_GlobalData management business.
First part of getting rid of CJS_RuntimeFactory. The factory design pattern isn't appropriate here since we only ever make one kind of object. CJS_GlobalData is now perfectly capable of managing itself through internal ref counts. I'm philosophically opposed to keeping ref-counts outside the object (do you hear me std::shared_ptr, you're bad!) R=thestig@chromium.org Review URL: https://codereview.chromium.org/1338993005 .
