[POWERPC] Fixup error handling when emulating a floating point instruction
When we do full FP emulation its possible that we need to post a SIGFPE based
on the results of the emulation. The previous code ignored this case completely.
Additionally, the Soft_emulate_8xx case had two issues. One, we should never
generate a SIGFPE since the code only does data movement. Second, we were
interpreting the return codes incorrectly, it returns 0 on success, 1 on
illop and -EFAULT on a data access error.
