Implement accurate arg reduction for the trig functions sin, cos, tan,

using __kernel_rem_pio2.  Use the accurate reduction in dd-%sin,
dd-%cos, dd-%tan.  The original version were renamed dd-%%sin,
dd-%%cos, dd-%%tan because we still need them to evaluate the
functions for small args.

This also has the side effect that we don't signal overflow for
moderately large args (~1w50) anymore.
