Modified Files:
        src/sys/arch/mips/include: cpuregs.h
        src/sys/arch/mips/mips: trap.c

Log Message:
Handle gas/gcc generating a break/trap 6 for integer overflow and
break/trap 7 for integer divide by zero and setting the SIGFPE
si_code of FPE_INTOVF or FPE_INTDIV respectively.  The break/trap
6/7 seems to have existed since the early days of MIPS but not
well documented anywhere.

Fixes ATF lib/libc/gen/t_siginfo::sigfpe_int .
