Description
After JDK-8339668 there is significant code duplication in management of the statistics counters for array chunking.

I.e. multiple classes add separate member variables, and the code added for that (updates and printing) has a significant amount of code duplication.

It would also be nice if the array chunking counters were printed next to the regular task queue counters, not below in separate lines.
Comments
Resolved as no longer an issue. Largely addressed by JDK-8345732. This part was not addressed: "It would also be nice if the array chunking counters were printed next to the regular task queue counters, not below in separate lines." The two sets of statistics (task queue counters and array chunking counters) are related but distinct, and merging them into one table doesn't seem like an improvement.
