CodeKind::OPTIMIZED_CODE -> TURBOFAN Kinds are now more fine-grained and distinguish between TF, TP, NCI. CodeKind::STUB -> DEOPT_ENTRIES_OR_FOR_TESTING Code stubs (like builtins, but generated at runtime) were removed from the codebase years ago, this is the last remnant. This kind is used only for deopt entries (which should be converted into builtins) and for tests.
