Bytecode parity (RustPython#7536)
* Add CFG block splitting, jump threading, backward jump normalization, genexpr StopIteration wrapper - split_blocks_at_jumps: split blocks at branch points so each has one exit - jump_threading: thread jumps through single-jump blocks (flowgraph.c jump_thread) - Backward conditional jump normalization: invert and create NOT_TAKEN+JUMP block - Follow empty blocks in jump-to-return optimization (next_nonempty_block) - Add PEP 479 StopIteration handler to compile_comprehension for generators * Add ConstantData::Slice and constant slice folding - Add Slice variant to ConstantData and BorrowedConstant - Fold constant slices (x[:3], x[1:4]) into LOAD_CONST(slice(...)) - Marshal serialization/deserialization for Slice type - Box::leak in borrow_obj_constant for PySlice roundtrip * Add duplicate_exits_without_lineno (disabled) and Block: Clone Prepare infrastructure for exit block duplication optimization. Currently disabled pending stackdepth integration. * Improve codegen bytecode parity
