        * flow.c (life_analysis_1): Break out some functions.
        (find_basic_blocks_1): Likewise.  Also move some variables out and
        make them static.
        Rename NONLOCAL_LABEL_LIST arg to NONLOCAL_LABELS and initialize
        new static var nonlocal_label_list with it.
        (active_eh_region, nested_eh_region, label_value_list,
        nonlocal_label_list): New static variables.
        (make_edges, delete_unreachable_blocks, delete_block): New static
        functions, broken out of find_basic_blocks_1.
        (record_volatile_insns, mark_regs_live_at_end, set_noop_p,
        noop_move_p): New static functions, broken out of life_analysis_1.
