RFR: 8316670: Remove effectively unused nmethodBucket::_count

Thu Sep 21 16:02:03 UTC 2023

Hi all,

  please review this removal of effectively dead code: `nmethodBucket::_count` is effectively dead code because as it's intended to be used as a refcount to check for mismatched add/remove calls, for some time now the remove-call has been removed, making the count obsolete.

Testing: gha

Thanks,
  Thomas
