It took a while, but I found the problem.  The fact that the prologue
generation code didn't use the same alignment that we applied at in
function.c.

Now that I think about it, I'm actually surprised that this *does*
work on x86_65 and ppc64.  An accident of pre-existing alignment, I assume.

I've reverted the patch til I can figure out the best way to proceed.
