[PATCH] testsuite/ubsan/overflow-div-3.c: Use SIGTRAP for MIPS

[YunQiang Su]

The DIV instructions of MIPS won't be trapped themself if the divisor
is zero.  The compiler will emit a conditional trap instruct for it.
So the signal will be SIGTRAP instead of SIGFPE.

        * c-c++-common/ubsan/overflow-div-3.c: Use SIGTRAP for MIPS.
