RFR: 8152639: ResourceMark missing in reportFreeListStatistics

[Stefan Karlsson]

Hi all,

Please review this ensure that a ResourceMark is used before the logging 
stream is used. The patch uses a LogStream instances, which embeds the 
ResourceMark.

I've manually verified that the output is the same.

Thanks,
