IIRC, I was trying to "fix" modeless operand by giving it a mode, but
since it made no difference for x86, I later dropped the patch.
However, operand with a known mode is preferred, so if it works for
you, just include my patch in your submission. My patch is somehow
trivial if we want operand to have known mode.
