    gcc-4.4: Add workaround for probable AMD cpu bug
    
    * Add a workaround to add a nop to the end of gcc-4.4's fill_sons_in_loop()
      function just prior to its return (to its multi-register pop and ret
      sequence).
    
      This works around what appears to be a aMD cpu bug in contemporary
      AMD cpus.
