I'm not sure why is this assert not needed anymore? (I'm also not sure why is
was needed before)

My reasoning: before only functions which allowed lazy compilation were
optimizable, now any function has a chance, hence the assert should go away. 
Does that sound reasonable?

-  // If optimization has been disabled for the shared function info,
-  // reflect that in the code object so it will not be counted as
-  // optimizable code.
-  ASSERT(value->kind() != Code::FUNCTION ||
-         !value->optimizable() ||
-         this->code() == Builtins::builtin(Builtins::Illegal) ||
-         this->allows_lazy_compilation());
   WRITE_FIELD(this, kCodeOffset, value);
   CONDITIONAL_WRITE_BARRIER(this, kCodeOffset, mode);
 }
