Fix i386/x86_64 log10l (sNaN) (bug 20228).
The i386/x86_64 versions of log10l 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 #20228] * sysdeps/i386/fpu/e_log10l.S (__ieee754_log10l): Add NaN input to itself. * sysdeps/x86_64/fpu/e_log10l.S (__ieee754_log10l): Likewise. * math/libm-test.inc (log10_test_data): Add sNaN tests.
