    [masm] Don't push CodeObject when entering INTERNAL frames · 75763183
    jgruber authored
    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.
