With floatx80_precision_x, the rounding happens across the break between words. Notice this case with frac_lsb = round_mask + 1 -> 0 and check the bits in frac_hi as needed. In addition, since frac_shift == 0, we won't implicitly clear round_mask via the right-shift, so explicitly clear those bits. This fixes rounding for floatx80_precision_[sd].
