Updates for ccosh[f] and csinh[f]stable/13

* lib/msun/src/s_ccosh.c:
  . Update Copyright years.
  . sin() and cos() are needed at the same time, so use sincos() to
    compute values.  This does argument reduction once instead of twice.
  . Replace '* 0.5' with '/ 2'. This reduces diff with s_ccoshf.c.
  . For (LDBL_MANT_DIG == 53), add weak references for ccoshl and ccosl.

  . Replace '* 0.5F' with '/ 2'. This reduces diff with s_ccoshf.c.
