        (struct local_info): New.
        (struct redirection_data): Add new INCOMING_EDGES and DO_NOT_DUPLICATE
        fields.
        (redirection_data): Now a hashtable.
        (redirection_data_hash, redirection_data_eq): New.
        (lookup_redirection_data, create_duplicates): New.
        (create_edge_and_update_destionation_phis): New.
        (fixup_template_block, redirect_edges): New.
        (thread_block): Use hash table traversals instead of loops over
        varray entries or incoming edge vectors.

        * tree-vectorizer.c (slpeel_tree_peel_loop_to_edge): Peeling scheme
        changed to suppoer uses-after-loop and to void creating flow paths
        that shouldn't exist.

        (rename_variables_in_bb): Don't update phis for BBs out of loop, to fit
        the new peeling scheme.
