Fix i386 asinhl (sNaN) (bug 20218).
The i386 version of asinhl returns sNaN (without raising any exceptions) for sNaN input. This patch fixes it to add non-finite arguments to themselves, so that "invalid" is raised and qNaN returned. Tested for x86_64 and x86. [BZ #20218] * sysdeps/i386/fpu/s_asinhl.S (__asinhl): Add non-finite argument to itself. * math/libm-test.inc (asinh_test_data): Add sNaN tests.
