Log Message:
- When zeroing/copying pages, use SSE2 movtni to avoid polluting the cache.
- By default, align assembly routines on 32-byte starting boundaries.
- There are now 8 interrupt priority levels, half of which are softints.
  Update intrdefs.h to match.
- Always clear/set spinlock words - removes lots of ifdefs.
- Remove the horrible ci_self150 hack that I introduced.
- Overhaul how TLB shootdown is performed. Inspired by a similar change in
  OpenBSD but implemented quite differently. This should be a lot faster
  but I have not benchmarked it yet.
