anymore. We can just use the MarkingBarrier in
main_thread_local_heap(). This makes code between main and background

* avoid CodeDataContainer <-> Code roundtrips when accessing writable
  state of Code objects via CodeT.

When pointer compression is disabled, and sizeof(Tagged_t) is 8 (eg,
arm64 without pointer compression), the function
extract_first_nonzero_index is never used, which was causing a warning.
