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).
