- Collapsed common checks between O0 and default
- Added Windows checks (would be great if someone could double-check these, the Microsoft docs that I've found are pretty vague).
- Fixed the patch to use the right register for the remainder. For this I had to basically bail out of FastISel, because it doesn't handle non-double multi-reg returns. I hope this hammer isn't too big for this problem, but getting FastISel to do the right thing here seemed like quite some work.
