How do I collapse it down to a const_int?
You use a constraint of 'n'.
Of course, you might get the fatal insn not recognized error, which is
pretty non-ideal as error messages go.  Hmmm.

Of course, now I am getting this for the correct test case that I am working on. Sigh. Maybe I will have better luck next week.
