  23         Initialize cst, reg, and rdisp inside the loop, for each
  24         new instruction.  Defer correction of the disp2 values until
  25         later, and then adjust them by the size of the first operand,
  26         rather than the size of the instruction.
  27         (sim_resume): For mova, adjust the size of the second operand
  28         according to the type of the first operand (INDEXB vs. INDEXW).
  29         In cases where there is only one operand, the other two must
  30         both be composed on the fly.
