Sorry, this didn't show up on pure x86_64.  It was caused by the
optabs.c patch rather than this one.  I've reverted it for now.

One fix would be:

  /* If the operand is a memory, try forcing the address into a register.  */
  if (MEM_P (op->value)
      && GET_RTX_CLASS (GET_CODE (XEXP (op->value, 0))) != RTX_AUTOINC
      && insn_data[(int) icode].operand[opno].allows_mem)

I think all other addresses really can be forced into registers.
