John Baldwin 3cf1f0c347 MFamd64: Various fatal page fault fixes.
- If a page fault is triggered due to reserved bits in a PTE, treat it
  as a fatal fault and panic.
- If PG_NX is in use, report whether a fatal page fault is due to an
  instruction fetch or a data access.
- If a fatal page fault is due to reserved bits in a PTE, report that as
  the page fault type rather than a protection violation.
