David Hildenbrand 24a2bd702c softfloat: add float128_is_{normal,denormal} ... Needed on s390x, to test for the data class of a number. So it will gain soon a user. A number is considered normal if the exponent is neither 0 nor all 1's. That can be checked by adding 1 to the exponent, and comparing against >= 2 after dropping an eventual overflow into the sign bit. While at it, convert the other floatXX_is_normal functions to use a similar, less error prone calculation, as suggested by Richard H.
