* tree-cfg.c (find_taken_edge_computed_goto): New function.
        (find_taken_edge): Call find_taken_edge_computed_goto as

        into a simple goto.
        (tree_merge_blocks): If block B has any forced labels, move
        them to the start of block A.
        * tree-ssa-dom.c (thread_across_edge): Allow threading across
        computed gotos as well.
        * tree-ssa-threadupdate.c (remove_ctrl_stmt_and_useless_edges): Handle
        removal of unnecessary computed gotos too.
        (lookup_redirection_data): Fix type of INSERT argument.  Callers
