 The final group consists of shift operations, where the shift amount is given first,
 and the value to shift is given second. Both arithmetic and logical right shifts are
 possible. The shift amount is encoded as a single byte, since only shift amounts
 between 0 and 31 are possible (only the low-order 5 bits of the shift amount are
 considered). The shift amount is given either as an immediate or in the single-
 byte register element %cl.
