   7    move is prefered for the  64-bit extract as it is either lower latency or
   8    the same latency as the extract instruction depending on the Endianess of
   9    the system.  Furthermore, there can be up to four move instructions in
  10    flight at a time versus only two extract intructions at a time.  */
