    libstdc++: Fix SFINAE for __is_intrinsic_type on ARM

    On ARM NEON doesn't support double, so __is_intrinsic_type_v<double,
    whatever> should say false (instead of being ill-formed).

    libstdc++-v3/ChangeLog:

            PR libstdc++/109261
            * include/experimental/bits/simd.h (__intrinsic_type):
            Specialize __intrinsic_type<double, 8> and
            __intrinsic_type<double, 16> in any case, but provide the member
            type only with __aarch64__.
