Speedup tanf range reduction
Speedup tanf range reduction by using the new sincosf range reduction algorithm. Overall code quality is improved due to inlining, so there is a speedup even if no range reduction is required. tanf throughput gains on Cortex-A72: * |x| < M_PI_4 : 1.1x * |x| < M_PI_2 : 1.2x * |x| < 2 * M_PI: 1.5x * |x| < 120.0 : 1.6x * |x| < Inf : 12.1x * sysdeps/ieee754/flt-32/s_tanf.c (__tanf): Use fast range reduction.
