* Makefile.in (OBJC-common): Add tree-ssa-threadupdate.c

        (tree-ssa-threadupdate.o): Add dependencies.
        * tree-ssa-threadupdate.c: New file.
        * tree-flow.h (incoming_edge_threaded): New flag in block annotation.
        (rewrite_vars_out_of_ssa): Remove prototype.
        (cleanup_tree_cfg): Returns a bool.
        * tree.h (thread_through_all_blocks): Prototype.
        * tree-outof-ssa.c  (SSANORM_*): Move into here.
        (remove_ssa_form): Now static.
        (rewrite_vars_out_of_ssa): Kill.
        * tree-ssa-live.c (register_ssa_partitions_for_vars): Kill.
        * tree-ssa-live.h (SSANORM_*): Moved into tree-outof-ssa.c.
        (remove_ssa_form, register_partitions_for_vars): Kill declarations.
        * tree-cfg.c (cleanup_tree_cfg): Return a value indicating if
        anything was changed.
        * tree-phinodes.c (add_phi_arg): Get the block for the PHI
        from the PHI's annotation rather than the edge associated with
        the new argument.
        * tree-ssa-dom.c (redirection_edges): Kill.
        (redirect_edges_and_update_ssa_graph): Kill.
        (tree_ssa_dominator_optimize): Do not reset forwardable flag
        for blocks anymore.  Do not initialize redirection_edges.
        Call thread_through_all_blocks.  Simplify code for cleanup
        of the CFG and iterating.  No longer call cleanup_tree_cfg
        outside the iteration loop.
        (thread_across_edge): No longer mess with forwardable blocks.
