The code doesn't seem to trap on a A500 which I believe is a PA8500.
I think we need to look at bits 0..1 of the coprocessor configuration
register to determine instruction validity.  See table 8-6 on page 8-11.
I can look at what the HP compiler does.  Up to now, we have assumed
that all PA8000 machines have the same instruction set.
