description:
When creating a SIGFPE siginfo for a gentrap, we have no additional info
(ucode) available, and the pal interface does not provide additional
details either. Hardcode the si_code value to FPE_INTDIV, since the only
callers of gentrap in our kernel seem to be the division routines in libkern.
