tcg: mark set_label with TCG_OPF_BB_END flag
set_label is effectively the end of a basic block, as no optimization can be made accross it. It was treated as such in the liveness analysis code, but as a special case. Mark it with TCG_OPF_BB_END flag so that this information can be used by other parts of the TCG code, and remove the special case in the liveness analysis code.
