Fix ldbl-128ibm sqrtl (sNaN) (bug 20153).
The ldbl-128ibm implementation of sqrtl wrongly returns an sNaN for signaling NaN arguments. This patch fixes it to quiet its argument, using the same x * x + x return for infinities and NaNs as the dbl-64 implementation uses to ensure that +Inf maps to +Inf while -Inf and NaN map to NaN. Tested for powerpc. [BZ #20153] * sysdeps/ieee754/ldbl-128ibm/e_sqrtl.c (__ieee754_sqrtl): Return x * x + x for infinities and NaNs.
