TurboFan compilation was committing dependencies long before the
optimized function made it's way into the optimized code list for
the native context. The problem is that once the code pointer is out
there in dependency arrays, it is eligible for deopt. But the deopt
logic needs the code to be in the optimized code list to fully do it's
job.
