refactor(llvm): Modularize instructions.rs into focused submodules by ChatGPT

Browse Source 
Successfully split the massive instructions.rs (1400+ lines) into organized submodules:

Structure:
- instructions/mod.rs - Module exports and wiring
- instructions/blocks.rs - Basic block creation and PHI setup
- instructions/flow.rs - Control flow (Return, Jump, Branch)
- instructions/externcall.rs - External call handling
- instructions/newbox.rs - NewBox operations
- instructions/boxcall.rs - BoxCall lowering (main dispatch)
- instructions/strings.rs - String fast-paths (concat, length)
- instructions/arrays.rs - Array operations (get/set/push/length)
- instructions/maps.rs - Map operations (size/get/set/has)
- instructions/arith.rs - Arithmetic operations (UnaryOp, BinOp, Compare)
- instructions/mem.rs - Memory operations (Load, Store)
- instructions/consts.rs - Constant value handling

Benefits:
- Improved maintainability (each file ~200-400 lines)
- Clear separation of concerns
- No behavior changes (pure refactoring)
- All existing smoke tests pass

# Current Task (2025-09-11)
# Current Task (2025-09-11) — Phase 15 LLVM‑only
> Phase 15 LLVM‑only notes (authoritative)
>
> - LLVM AOT is the stable/authoritative path. VM/Cranelift JIT/AOT and the interpreter are not MIR14‑ready in this phase.
> - Fallback logic must be minimal. Prefer fixing MIR type annotations over adding broad implicit conversions.
> - ExternCall (console/debug) selects C‑string vs handle variants by the argument IR type.
> - StringBox: NewBox keeps i8* fast path (no birth); print/log choose automatically based on IR type.
Summary
- LLVM is the authoritative path; VM/Cranelift/Interpreter are not MIR14‑ready.
- Keep fallbacks minimal; fix MIR annotations first.
- ExternCall(console/debug) auto‑selects ptr/handle by IR type.
- StringBox NewBox i8* fast path; print/log choose automatically.
Done (today)
- BoxCall legacy block removed in LLVM codegen; delegation only.
- BinOp concat safety: minimal fallback for i8*+i64/i64+i8* when both sides are annotated String/Box → from_i8_string + concat_hh; otherwise keep concat_ss/si/is.
- String fast‑path: length/len lowered to nyash.string.len_h (handle), with ptr→handle bridge when needed.
- Map core‑first: NewBox(MapBox) routes via nyash.env.box.new("MapBox") → NyRT特例でコアMapを生成。LLVM BoxCall(Map.size/get/set/has) は NyRT の nyash.map.* を呼ぶ。
- Plugin強制スイッチ: NYASH_LLVM_FORCE_PLUGIN_MAP=1 で MapBox のプラグイン経路を明示切替（デフォルトはコア）。
- Docs: ARCHITECTURE/LOWERING_LLVM/EXTERNCALL/PLUGIN_ABI を追加・整備。
- Smokes: plugin‑ret green, map smoke green（core‑first）。
Next — Refactor instructions.rs (no behavior change)
- Goal: Make `src/backend/llvm/compiler/codegen/instructions.rs` maintainable (now >1400 lines).
- Plan (split into focused submodules under `codegen/`):
- `instructions/externcall.rs` — env.console/debug, readline
- `instructions/boxcall.rs` — generic BoxCall lowering, by‑id/tagged paths glue
- `instructions/newbox.rs` — NewBox + birth/env.box.new bridge
- `instructions/strings.rs` — concat fast‑paths, length/len (later: substring/indexOf/replace/trim/toUpper/toLower)
- `instructions/arrays.rs` — get/set/push/length
- `instructions/maps.rs` — size/get/set/has (core NyRT shims)
- `instructions/arith.rs` — UnaryOp/BinOp/Compare (includes concat fallback)
- `instructions/flow.rs` — Return/Branch/Jump/PHI finalize
- Keep `types.rs` for helpers; keep `create_basic_blocks`/`precreate_phis` in a small `blocks.rs` if needed.
- Constraints:
- 0‑diff behavior for existing smokes; no fallback拡大。
- No new deps; keep function signatures stable; pub(super) only.
- Update mod wiring in `codegen/mod.rs` accordingly.
After refactor (follow‑ups)
- Expand String AOT fast‑paths: substring/indexOf/replace/trim/toUpper/toLower.
- Remove temporary env.box.new(MapBox) special‑case by moving MapBox生生成 into a dedicated NyRT entry.
- Tighten MIR annotations for Map.get returns in common patterns.
- Add targeted smokes after each implementation step（実装後にテスト）。
Risks/Guards
- Avoid broad implicit conversions; keep concat fallback gated by annotations only.
- Ensure nyash.map.* との一致（core Map）; plugin経路は環境変数で明示切替。
- Keep LLVM smokes green continuously; do not gate on VM/JIT.
