Rename the DIV0 traps to avoid confusion with the usage on the sparc 

port: T_IDIV0 is the hardware trap generated on integer division by
zero, T_DIV0 is the software trap used to signal the same event.

This makes 32 bit kernels able to run sparc code with the v7 multiply/
divide library, as well as with the v8 one.
