Consolidate sincos computation for 2.426265 < |x| < 105414350
Like the previous change, exploit the fact that computation for sin and cos is identical except that it is apart by a quadrant. Also remove csloww, csloww1 and csloww2 since they can easily be expressed in terms of sloww, sloww1 and sloww2.
