Currently a divu with a zero divisor causes a floating point exception and banshee crashes.
According to the RISC-V ISA manual a division by zero is clearly defined and should not result in an exception.
The value of all bits set is returned for both unsigned and signed divide by zero to simplify the divider circuitry.
This can easily be implemented in banshee
