    ipa/94947 - avoid using externally_visible_p ()

    externally_visible_p wasn't the correct predicate to use (even if it
    worked), instead we should use DECL_EXTERNAL || TREE_PUBLIC.

            * tree-ssa-structalias.c (refered_from_nonlocal_fn): Use
            DECL_EXTERNAL || TREE_PUBLIC instead of externally_visible.
            (refered_from_nonlocal_var): Likewise.
            (ipa_pta_execute): Likewise.
