flow.c (struct propagate_block_info): Add new_dead, new_live.

        * flow.c (struct propagate_block_info): Add new_dead, new_live.
        (propagate_block): Initialize them.  Use them in parallel instead
        of one tmp variable, ie revert much of the 0408 and 0407 functional
        changes, but keep the structural changes.
        (mark_set_regs): Take new_dead from propagate_block_info instead.
        (mark_set_1, mark_set_reg): Likewise.
        (mark_used_regs): Likewise with new_live.
        (mark_used_reg): Likewise.  Revert 0408 change.
