Original Commit Message:

    The code slot of internal frames seems to be basically unused.
    As always, there are exceptions:

    1. In elements.cc we check whether the current code object is the apply
    builtin. We can use a heap lookup through the frame's pc instead.
    2. In isolate.cc we store a reference to the frame's code object to try
    and pack it into the minidump. This can safely be skipped.

    Remaining use-sites in frames.cc all skip INTERNAL frames by using the
    JavaScriptFrameIterator.
