I don't think I break the math-emu. I think the codes I added have
no impact to the existing math-emu.

I'd like to do this, but in most handler codes, I can't find copyright information
of the orig authors. I think the math-emu code comes from glibc. In the
sigfpe_handler.c, I gave credit to the orig author.

I think the SPEFloatingPointRound exception is not necessary to handle if we
handle floating point exception this way.
