    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.
