I guess this is fine.  LGTM

Ultimately, the whole design here is sort of flaky: the scheduling code here isn't aware of register pressure, and the register allocator isn't aware of the possibility of generating ldm/stm, so the end result is very unreliable.  I'm not sure what the right solution is, but tweaking the scheduling heuristics isn't going to help much.
