LiveInfo 四矩阵由逐位 Vec<bool>（1 字节/位，长度 = max_vreg+1）改为 u64 压缩位集（1 字 64 位，长度 ÷8），dataflow 不动点 out/input 缓冲 提为循环外复用（clear + 覆盖，免逐迭代逐块分配）。dce_precise / graph 建图 / call_window 三处消费方同步改为字内位移查询，越界语义 与旧 Vec<bool>::get 一致（越界 = 不 live）。位集遍历（call_window 存活上界）按 trailing_zeros 只走实际置位，活集小则近 O(活集) 而非 O(254)。 实测（debug，start-unicode-17.0.0.js）：liveness 三趟合计 ~536ms → ~118ms（-78%），矩阵内存 ÷8；graph 全 node 扫描为剩余 瓶颈，另行跟进。
