MFC r271747:
 - Use NULL instead of 0 for fpcurthread.
 - Note the quirk with the interrupt enabled state of the dna handler.
 - Use just panic() instead of printf() and panic().  Print tid instead
   of pid, the fpu state is per-thread.

Update and clarify comments.  Remove the useless counter for impossible, but
