        * tree.h (GIMPLE_TUPLE_P): Also true for PHI_NODEs.
        (GENERIC_NEXT): New function macro.
        (PHI_CHAIN): Use phi_node's new chain variable.
        (tree_phi_node): Change tree_common to tree_base
        and add the chain field.
        * tree-phinodes.c (make_phi_node): Don't set
        TREE_TYPE on the new node.
        * c-decl.c (lang_tree_node): Use GENERIC_NEXT
        instead of checking GIMPLE_TUPLE_P in chain_next.
        * tree-vect-transform.c
        (get_initial_def_for_induction): Look at
        PHI_RESULT_TREE for the type of the phi node.
        (update_vuses_to_preheader): Use PHI_CHAIN
        instead of TREE_CHAIN on the phi node.
        * tree-ssa-structalias.c (compute_points_to_sets):
        Likewise.
        (ipa_pta_execute): Likewise.
