Fix i386/x86_64 log1pl (sNaN) (bug 20229).
The i386/x86_64 versions of log1pl return sNaN for sNaN input. This patch fixes them to add a NaN input to itself so that qNaN is returned in this case. Tested for x86_64 and x86. [BZ #20229] * sysdeps/i386/fpu/s_log1pl.S (__log1pl): Add NaN input to itself. * sysdeps/x86_64/fpu/s_log1pl.S (__log1pl): Likewise. * math/libm-test.inc (log1p_test_data): Add sNaN tests.
