And the 68040 improves them even more... except that it improves the speed
of the *simple* stuff by a much larger margin.  Nobody is going to optimize
for the 030 and ignore the 040 at this point... and the list of fast modes
on the 040 is the original 68000 mode list minus indexed.  Not one of the
new-on-020 modes is included; they all take the slow path.
