Fix i386/x86_64 log2l (sNaN) (bug 20235).
The i386/x86_64 versions of log2l return sNaN for sNaN input. This patch fixes them to add NaN inputs to themselves so that qNaN is returned in this case. Tested for x86_64 and x86. [BZ #20235] * sysdeps/i386/fpu/e_log2l.S (__ieee754_log2l): Add NaN input to itself. * sysdeps/x86_64/fpu/e_log2l.S (__ieee754_log2l): Likewise. * math/libm-test.inc (log2_test_data): Add sNaN tests.
