JDK-8220311 - Implementation: NUMA-Aware Memory Allocation for G1, Survivor (2/3)
Description
If node index is added at G1HeapRegionAttr, we may simplify some codes such as G1ParScanThreadState::copy_to_survivor_space(G1HeapRegionAttr, , )

Investigate and change if we can get some benefit.
This idea was brought up during discussion / review of JDK-8220311.
