softfloat: Inline float64 compare specializations
Replace the float64 compare specializations with inline functions that call the standard float64_compare{,_quiet} functions. Use bool as the return type. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
