Fix ldbl-128 expm1l (sNaN) (bug 20232).
The ldbl-128 version of expm1l returns sNaN for sNaN input.  This
patch fixes it to add such inputs to themselves so that qNaN is
returned in this case.

Tested for mips64.

	[BZ #20232]
	* sysdeps/ieee754/ldbl-128/s_expm1l.c (__expm1l): Add NaN input to
	itself.
