Fix dbl-64 asin (sNaN) (bug 20213).
The dbl-64 version of asin returns sNaN for sNaN arguments. This patch fixes it to add NaN arguments to themselves so that qNaN is returned in this case. Tested for x86_64 and x86. [BZ #20213] * sysdeps/ieee754/dbl-64/e_asin.c (__ieee754_asin): Add NaN argument to itself. * math/libm-test.inc (asin_test_data): Add sNaN tests.
