George Koehler f33b30ed3c Rewrite .fif8 to avoid powerpc64 fctid
This fixes the SIGILL (illegal instruction) in startrek when firing
phasers.  The 32-bit processors in my PowerPC Mac and in QEMU don't
have fctid, a 64-bit instruction.

I got the idea from mach/proto/fp/fif8.c to extract the exponent,
clear some bits to get an integer, then subtract the integer from
the original value to get the fraction.
