Log message:
        Minor optimization of fp_rempio2(), which is used in sin(), cos()
        and tan() functions. The size of libm is reduced by 11 words. Speed
        of sin/cos/tan is increased a little in average, besides the interval
        from 1 to Pi/2 radians, where the performance is worsen by 6 cycles.
        Thanks to Ruud v Gessel.
        * libm/fplib/fp_rempio2.S: Rewritten to reduce size.
        * libm/fplib/fp_mpack.S: Reduce size by 2 words. Add extra entry
        __fp_mpack_finite().
        * tests/simulate/math/fp_mpack-01.c: New file.
        * doc/api/bench-libm.dox: Update calculation times.
        * NEWS: Note about sin/cos/tan optimization.
