MFC 233925,236357:
Add new ktrace records for the start and end of VM faults.  This gives
a pair of records similar to syscall entry and return that a user can
use to determine how long page faults take.  The new ktrace records are
enabled via the 'p' trace type, but are not enabled in the default set of
trace points.
