Wilco Dijkstra e88ecbbfe8 [PATCH 7/7] sin/cos slow paths: refactor sincos implementation 
Refactor the sincos implementation - rather than rely on odd partial inlining
of preprocessed portions from sin and cos, explicitly write out the cases.
This makes sincos much easier to maintain and provides an additional 16-20%
speedup between 0 and 2^27.  The overall speedup of sincos is 48% over this range.
Between 0 and PI it is 66% faster.

	* sysdeps/ieee754/dbl-64/s_sin.c (__sin): Cleanup ifdefs.
	(__cos): Likewise.
	* sysdeps/ieee754/dbl-64/s_sin.c (__sincos): Refactor using the same
	logic as sin and cos.
