Pretty cool.  I'm pretty sure there's some stuff in this patch that's
not right in detail, but I think this is an awfully exciting
direction.

I'd like to commit David Rowley's patch from the other thread first,
and then deal with this one afterwards.  The only thing I feel
strongly needs to be changed in that patch is CFUNC -> COMBINEFUNC,
for clarity.
