Joseph Myers d73e7bdb3a Fix ldbl-128 j0l, j1l, y0l, y1l for sNaN argument (bug 20151).
The ldbl-128 implementations of j0l, j1l, y0l, y1l (also used for
ldbl-128ibm) return an sNaN argument unchanged.  This patch fixes them
to add a NaN argument to itself to quiet it before return.

Tested for mips64.

	[BZ #20151]
	* sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_j0l): Add NaN
	argument to itself before returning result.
	(__ieee754_y0l): Likewise.
	* sysdeps/ieee754/ldbl-128/e_j1l.c (__ieee754_j1l): Likewise.
	(__ieee754_y1l).
