RFR: 8232601: ZGC: Parameterize the ZGranuleMap table size

[Stefan Karlsson]

Hi all,

Please review this patch to parameterize the ZGranuleMap table size.

https://cr.openjdk.java.net/~stefank/8232601/webrev.01/
https://bugs.openjdk.java.net/browse/JDK-8232601

Previously, the maps were always bound by the range of a virtual address 
space view (ZAddressOffsetMax). We want to be able to use ZGranuleMap to 
map against physical memory offsets, so this RFE suggests that we allow 
users of ZGranuleMap to specify the max offset.

Thanks,
StefanK
