Alex Bennée c13bb2da9e fpu/softfloat: re-factor sqrt ... This is a little bit of a departure from softfloat's original approach as we skip the estimate step in favour of a straight iteration. There is a minor optimisation to avoid calculating more bits of precision than we need however this still brings a performance drop, especially for float64 operations.
