Include s_sin.c in s_sincos.c
Include the __sin and __cos functions as local static copies to allow deper optimization of the functions. This change shows an improvement of about 17% in the min case and 12.5% in the mean case for the sincos microbenchmark on x86_64. * sysdeps/ieee754/dbl-64/s_sin.c (__sin)[IN_SINCOS]: Mark function static and don't set or restore rounding. (__cos)[IN_SINCOS]: Likewise. * sysdeps/ieee754/dbl-64/s_sincos.c: Include s_sin.c. (__sincos): Set and restore rounding mode. Remove check for infinite or NaN input.
