IR optimization passes: constant folding, superinstructions, jump nor… 
…malization

- Binary op constant folding with Python floor-div/modulo semantics
- Unary negative folding into LOAD_CONST, with binop re-run
- Tuple/list/set/frozenset constant folding
- STORE_FAST_LOAD_FAST combination (insert_superinstructions before optimize_load_fast)
- JUMP → RETURN_VALUE inlining (normalize_jumps)
- RESUME depth correction for StopIteration wrapper
- DCE, unreachable block elimination, duplicate_end_returns
