Fix i386 atanhl (sNaN) (bug 20219).
The i386 version of atanhl returns sNaN for sNaN input. This patch fixes it to add NaN arguments to themselves so it returns qNaN in this case. Tested for x86_64 and x86. [BZ #20219] * sysdeps/i386/fpu/e_atanhl.S (__ieee754_atanhl): Add NaN argument to itself. * math/libm-test.inc (atanh_test_data): Add sNaN tests.
