 *  4) if |x| <   Pi/4: return x+x^3*(S0+x^2*(S1+x^2*(S2+x^2*(S3+x^2*S4)))).
 *  5) if |x| < 9*Pi/4:

 *           t=|x|-j*Pi/4.

 *          if(n&2 != 0) {

 *          }
 *  6) if |x| < 2^23, large args:
 *      6.1) Range reduction: k=trunc(|x|/(Pi/4)), j=(k+1)&0xfffffffe, n=k+1,
 *           t=|x|-j*Pi/4.
 *      6.2) Reconstruction same as (5.2).
 *  7) if |x| >= 2^23, very large args:

 *      7.2) Reconstruction same as (5.2).
 *  8) if x is Inf, return x-x, and set errno=EDOM.
 *  9) if x is NaN, return x-x.
 *
 * Special cases:
 *  sin(+-0) = +-0 not raising inexact/underflow,
 *  sin(subnormal) raises inexact/underflow,
 *  sin(min_normalized) raises inexact/underflow,
 *  sin(normalized) raises inexact,
 *  sin(Inf) = NaN, raises invalid, sets errno to EDOM,
 *  sin(NaN) = NaN.
