* sysdeps/ieee754/dbl-64/s_sin.c (t22): Consolidate const
definition...
(slow1, slow2, sloww1, sloww2, bsloww1, bsloww2, cslow2,
csloww1, csloww2): ... from here.
* sysdeps/ieee754/dbl-64/usncs.h: Define constants as double
instead of structures.
* sysdeps/ieee754/dbl-64/s_sin.c (POLYNOMIAL2): Adjust.
