Thanks for doing this!  It's been on my TODO list for a little while already for SPE, but I never got around to it.

Is there any provision for spilling only the subreg, not the superreg?  It seems to me that whenever the subreg needs spilled, it always also spills the superreg, even if the full superreg is not used.
