Log Message:
Instrument the lazy FP context switch path:
- fpevent_use is incremented the first time a process uses FP
  for the first time (note, FPUSED is inherited on fork, but
  cleared on exec).
- fpevent_reuse is incremented whenever a process that has previously
  used FP has to take a FEN trap in order to be able to use it again.
