Joseph Myers 499a2f7b55 softfloat: fix floatx80 remainder pseudo-denormal check for zero
The floatx80 remainder implementation ignores the high bit of the
significand when checking whether an operand (numerator) with zero
exponent is zero.  This means it mishandles a pseudo-denormal
representation of 0x1p-16382L by treating it as zero.  Fix this by
checking the whole significand instead.
