> Some architectures (like powerpc) provide status information on the exact
> type of invalid exception. This is pretty straight forward as we already
> report invalid exceptions via FP_SET_EXCEPTION.
>
> We add new flags (FP_EX_INVALID_*) the architecture code can define if it
> wants the exact invalid exception reported.
>
> We had to split out the INF/INF and 0/0 cases for divide to allow reporting
