As documented in eclipse-openj9/openj9#9712, initial attempt to fix the SplitPostGRA to work with RegDepCopyRemoval resulted in 5% regression in performance throughput on x86 which required us to disable the RegDepCopyRemoval when value types are enabled. Later on the performance issue was addressed and fixed. This PR reverts the change that disabled RegDepCopyRemoval when value types are enabled. Signed-off-by: Rahil Shah <[email protected]>
