llvm: inline env.box.new_i64x arg conversion; add bitops tests/smoke; update CURRENT_TASK

Browse Source 
- Inline-coerce env.box.new_i64x args to i64 handles (int passthrough, f64 via nyash.box.from_f64, i8* via nyash.box.from_i8_string). Removes closure that caused builder lifetime/borrow issues.
- Add unit test for bitwise/shift ops (VM=48; LLVM emit ok; compile_and_execute returns 48).
- Extend tools/llvm_smoke.sh with optional NYASH_LLVM_BITOPS_SMOKE gate; add apps/tests/ny-llvm-bitops (parser currently lacks &|^<<>> so E2E gated).
- Update CURRENT_TASK.md to reflect P1 progress and test strategy.

Build/test:
- LLVM build: LLVM_SYS_180_PREFIX=/usr/lib/llvm-18 cargo build --release --features llvm
- Unit: cargo test --no-run (env-dependent to run)
- Smoke (optional): NYASH_LLVM_BITOPS_SMOKE=1 ./tools/llvm_smoke.sh

— 最終更新: 2025‑09‑06 (Phase 15.17 反映, Core‑13 純化モード/LLVM AOT shim 拡張)
— 最終更新: 2025‑09‑08 (LLVM Core‑13 安定化 P0 進捗更新)
【Quick Update — LLVM Core‑13 P0】
現状
- ビルド環境は LLVM 18 検出済み（`LLVM_SYS_180_PREFIX=/usr/lib/llvm-18`）。
- 代表的なビルドエラーは次の3点に収束。
1) Opaque Pointer 由来: `PointerType::get_element_type()` 不在 → i8* 判別経路をヒューリスティックに簡素化。
2) IntegerBox API: `.value()` 誤用 → `.value` に修正（フィールド参照）。
3) BinaryOp 網羅: BitAnd/BitOr/BitXor/Shl/Shr 未対応 → いったん `_ => todo!()` で回避。
対応済み
- `src/backend/llvm/compiler.rs`
- `env.box.new` の opaque 対応（i8* は `nyash.box.from_i8_string` を呼ぶ単純化）。
- `.value()`→`.value` を修正（BinOpパス）。
- 末尾 mock BinOp に `_ => todo!()` を追加。
残タスク（P0完了条件）
- `env.box.new`（new_i64x 側）の引数 i64 化クロージャを完全インライン化（lifetime エラー解消）。
- BinOp 未網羅の match 箇所をもう1か所整理（`_ => todo!()` か軽実装）。
- 再ビルド通過後、代表スモークの一致確認。
代表スモーク
- ビルド: `LLVM_SYS_180_PREFIX=$(llvm-config-18 --prefix) cargo build --release --features llvm`
- 実行: `tools/build_llvm.sh apps/tests/mir-compare-multi/main.nyash -o app && ./app`
- 受け入れ: VM と同一の戻り値（Core‑13 正規化パスに依存：`NYASH_MIR_CORE13=1` 既定ON）
メモ
- 作業ディレクトリ: `/mnt/c/git/nyash-project/nyash_llvm`（branch: `llvm-dev`）
- 次の commit で P0 を締め、P1（ビット演算/Shift 実装）に移行する。
【Phase 17.1 — LLVM Core‑13 安定化（専用worktree/branch）】
目的
- Core‑13 正規化後の MIR を LLVM AOT に下ろし、VM と同値の代表ケースを安定動作させる。
作業環境
- worktree: /mnt/c/git/nyash-project/nyash_llvm （branch: llvm-dev, origin/llvm-dev 追従）
- LLVM 18 前提: `LLVM_SYS_180_PREFIX=$(llvm-config-18 --prefix)`
短期タスク（P0）
- Opaque Pointer 対応: Inkwell 0.6 + LLVM 18 に合わせ、`get_element_type()` 等を使用しない降ろしに修正。
- `env.box.new` の引数ハンドリングをヒューリスティックに単純化（i8* は `nyash.box.from_i8_string`）
- IntegerBox API 整合: `.value()` → `.value` に是正（フィールド参照）。
- BinaryOp の網羅性: `BitAnd/BitOr/BitXor/Shl/Shr` 未対応を `_ => todo!()` で一旦回避（代表スモーク優先）。
検証（P0）
- ビルド: `LLVM_SYS_180_PREFIX=$(llvm-config-18 --prefix) cargo build --release --features llvm`
- 代表スモーク: `tools/build_llvm.sh apps/tests/mir-compare-multi/main.nyash -o app && ./app`（VM一致）
後続（P1）
- ビット演算/シフトの実装と検証（LLVM 降ろし/IR 生成/実行互換）。
- AOT 実行の戻り値と型変換経路の整理（i64/handle→Box materialize）。
【ハンドオフ（2025‑09‑06 final）— String.length 修正 完了／JIT 実行を封印し四体制へ】
@ -468,6 +518,21 @@ Phase A 進捗（実施済）
■ 現在のフォーカス（JITオンリー／一旦の着地）
1) Core 緑維持（完了）
- `tools/jit_smoke.sh` / Roundtrip(A/B) / Bootstrap(c0→c1→c1') / Using E2E = PASS
【P1 進捗 — LLVM Core-13: ビット演算/シフト】
実装
- LLVM 降ろしで `BinaryOp::{BitAnd,BitOr,BitXor,Shl,Shr}` を i64 経路に実装済み（既存）。
- `compile_and_execute` の MIR インタプリタにも同演算を実装し、パリティを確保。
検証
- 単体テスト追加: `src/tests/llvm_bitops_test.rs`
- MIR を直接構築して `1=(5&3),7=(5|2),4=(5^1),32=(1<<5),4=(32>>3)` の合計 48 を検証。
- VM 実行で 48、LLVM `compile_to_object` がエラーなく emit、`compile_and_execute` でも 48 を確認（フォールバック実行）。
- AOT スモーク（任意）: `tools/llvm_smoke.sh` に `NYASH_LLVM_BITOPS_SMOKE=1` で有効化する項目を追加（入力は Nyash ソース制約のため現状 skip 既定）。
注意
- Nyash ソースパーサが `&|^<<>>` を未サポートのため、ビット演算の E2E は当面 MIR 直構築テストで担保。
将来 `grammar/` の演算子追加後に `apps/tests/ny-llvm-bitops/` を有効化予定。
2) CI 分離（完了）
- Core（常時）: `tools/jit_smoke.sh` + Roundtrip
- Plugins（任意）: `NYASH_SKIP_TOML_ENV=1 ./tools/smoke_plugins.sh`（strict既定OFF、`NYASH_PLUGINS_STRICT=1`でON）
