Update spilling transform for async and generator functions to not require a defined attribute bitfield. We now treat temporary spilled values with overlapping error values as always defined. I'm not sure if this would be safe to do for reference counted values, so we only do this in cases where it's clearly fine.

Update spilling transform for async and generator functions to not requirea defined attribute bitfield. We now treat temporary values with overlappingerrors values as always defined. This would be more difficult to do forreference counted values, so we don't do this for all values.
