MFC 196705 and 196707:
- Improve pmap_change_attr() on i386 so that it is able to demote a large
  (2/4MB) page into 4KB pages as needed.  This should be fairly rare in
  practice.
- Simplify pmap_change_attr() a bit:
  - Always calculate the cache bits instead of doing it on-demand.
  - Always set changed to TRUE rather than only doing it if it is false.
