Dynarec ( JIT ) IR vs Interpreter IR comparision ?

[LunaMoo]

There's no such thing as JIT IR, you can either use:
- JIT,
- IR interpreter,
- interpreter.

That's listed from fastest to slowest, exact difference is pretty pointless since it will differ a lot per game, JIT will always be the fastest one and so is default on platforms that can have JIT. Which includes everything except iOS where apple loves to break it with every system update.

IR interpreter might still be worth trying against games which are broken in the other two as it works a bit differently, it's existence already proved very useful in revisiting some ancient issues.
