against doing this for floating point (!Op0->getType()->isFPOrFPVector()).

void func(double *rhi, double *rlo, double xh, double xl, double yh, double yl){

The last line was optimized away, but rl is intended to be the difference
between the infinitely precise result of mh + ml and after it has been rounded
to double precision.
