Wilco Dijkstra 900fb446eb 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.
