Description: Add mark_cold, push_cold_blocks_to_end, and normalize_jumps passes to the codegen CFG pipeline. Use JumpNoInterrupt for exception handler exit paths in try-except-finally compilation. Summary by CodeRabbit Bug Fixes Improved exception/unwinding behavior to better manage interrupts during cleanup paths. Refactor Reordered cold/infrequently-used code blocks to the end for more efficient layout. Normalized jump/control-flow sequences to reduce redundant transitions and improve stability. Tests Updated runtime and debug handling so no-op markers are ignored during execution and annotation output.
