This version seems to work all right, but it generates illegal instruction
sequences.  I was informed by Motorola that there is a post-optimizer
that is required, and that this code was not made freely available.
Although I was able to hack up a simple peephole optimizer to get rid
of the illegal instructions, the gcc code is very inefficient.
I threw the whole thing away.  Perhaps Motorola worked very hard
on their optimizer and it does miraculous things.  Perhaps not.
