Fix program end by exception if divisor is zero for div instruction.
Problem reported by Jakub Broz. Correct behaviour according to MIPS Architecture for Programmers Volume II-A: The MIPS32 Instruction Set Manual which describes DIV instruction Format: DIV rs, rt No arithmetic exception occurs under any circumstances. Restrictions: If the divisor in GPR rt is zero, the arithmetic result value is UNPREDICTABLE. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
