  Log:
  Rearrange the polynomial evaluation for better parallelism.  This
  saves an average of about 8 cycles or 5% on A64 (amd64 and i386 --
  more in cycles but about the same percentage on i386, and more with
  old versions of gcc) with good CFLAGS and some parallelism in the
  caller.  As usual, it takes a couple more multiplications so it will
  be slower on old machines.
  
  Convert to __FBSDID().
