Description
The G1PrintRegionLivenessInfo parameter is currently a product parameter. We should make it diagnostic. Generating the output required by this parameter involves doing a serial iteration over all the regions in the heap, which might introduce a scalability bottleneck for the GC pauses that observe this parameter.
