      original commit message:
      The previous approach taken by FastNew[Sloppy,Strict,Rest]ArgumentsStub
      looked at the function slot in order to skip stub frames
      and find the JS frame. However, stub frames do not have a
      function slot (in fact their fixed frame ends one slot
      before the JS frame's function slot). Therefore, if this
      location in the stub frame happens to have the function
      object the create arguments stubs won't skip this frame
      correctly.
    
      Replace this approach with one where the stub is
      specialized to either skip a frame if required (since
      there will only ever be one extra frame on Ignition
      the loop approach isn't necessary).
