This PR adds
--yjit-trace-exits=COUNTERwhich allows you to trace a specific counted exit.By default,
--yjit-trace-exitscounts all exits, so it's unclear why each instruction exited since every type of exits is mixed up. This option allows you to filter out unrelated kinds of exits and focus on a particular exit. It can also speed up the tracing process if there are too many unrelated exits.
