Improvement CORE-4935 : Increase performance of backout of dead record version (or undo of just created primary record version) when backversions chain is too long
...
Improvement CORE-4936 : Reduce internal contention in background garbage collector
Other small improvements:
- garbage collector\sweep now skip record header if transaction is below OIT - it allows to reduce number of page fetches
- missed points to gather RECORD_FRAGMENT_READS and RECORD_BACKVERSION_READS statistics
