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