You are adding 2 types of such ifdef's.
The permanent ones and the temporary ones (such as this one) until arm64 is
fully implemented. I would mark the temporary ones with a TODO(zra), especially
when they are not at the top of a file.
It will be easier for you later to hunt for them again.

Done.

   if (snapshot_buffer == NULL) {
     if (!isolate->object_store()->PreallocateObjects()) {
       return isolate->object_store()->sticky_error();
     }
   }

   isolate->heap()->EnableGrowthControl();
   isolate->set_init_callback_data(data);
