[MINOR] Enhance SizeEstimator to detect IBM compressed refs and s390 …
…arch.
- zSeries 64-bit Java reports its architecture as s390x, so enhance the 64-bit check to accommodate that value.
- SizeEstimator can detect whether IBM Java is using compressed object pointers using info in the "java.vm.info" property, so will do a better job than failing on the HotSpot MBean and guessing.
