math: Improve fmod(f) performance
Optimize the fast paths (x < y) and (x/y < 2^12). Delay handling of special cases to reduce the number of instructions executed before the fast paths. Performance improvements for fmod: Skylake Zen2 Neoverse V1 subnormals 11.8% 4.2% 11.5% normal 3.9% 0.01% -0.5% close-exponents 6.3% 5.6% 19.4% Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
