RFR (S): 8008536: Add HotSpot support for printing class loader statistics for JMap

[Erik Helin]

All,

based on some internal feedback, I've updated the change.
The file PermStat.java can be removed already in this first change. This
means that 'hg mv' can be used, which provides a better history.

Webrev:
http://cr.openjdk.java.net/~ehelin/8008536/webrev.01/

The second and third change have also been updated.

Thanks,
Erik
