This seems to violate our naming standard that we had which states use lower
case names which match the field name for accessors otherwise use camel case
names.

Why are you not calling the accessor dependent_code() ??

Renamed the accessors to [set_]dependent_code and added a comment to match those
on LibraryPrefix and Field.

   void set_cha_codes(const Array& value) const;
 
   bool TraceAllocation(Isolate* isolate) const;
