Jakob Gruber 29bcdaad1d Rename legacy code kinds 
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.
