[PATCH] Don't consider zero succs empty blocks as forwarders (PR rtl-optimization/71916)

Hi! Normally empty blocks without successors (result of __builtin_unreachable () somewhere in RTL) aren't considered as forwarder_block_p, because they don't satisfy single_succ_p. But e.g. during cross-jumping fake edges to exit are added and then they suddenly satisfy this predicate, which
