A案実装: debug_verify_phi_inputs呼び出し前にCFG predecessorを更新
修正箇所（7箇所）:
- src/mir/builder/phi.rs:50, 73, 132, 143
- src/mir/builder/ops.rs:273, 328, 351
根本原因:
- Branch/Jump命令でsuccessorは即座に更新
- predecessorはupdate_cfg()で遅延再構築
- PHI検証が先に実行されてpredecessor未更新でpanic
解決策:
- 各debug_verify_phi_inputs呼び出し前に
if let Some(func) = self.current_function.as_mut() {
func.update_cfg();
}
を挿入してCFGを同期
影響: if/else文、論理演算子(&&/||)のPHI生成が正常動作
