[PATCH 2/4] softfloat: fix floatx80 pseudo-denormal addition / subtraction

The softfloat function addFloatx80Sigs, used for addition of values with the same sign and subtraction of values with opposite sign, fails to handle the case where the two values both have biased exponent zero and there is a carry resulting from adding the significands, which can occur if one or
