        here.
        * omp-low.c (create_omp_child_function): Remove "omp declare simd"
        attributes from DECL_ATTRIBUTES (decl) without affecting
        DECL_ATTRIBUTES (current_function_decl).
        * omp-simd-clone.c (expand_simd_clones): Ignore DECL_ARTIFICIAL
        functions with non-NULL DECL_ABSTRACT_ORIGIN.
