[11u] RFR: 8185005: Improve performance of ThreadMXBean.getThreadInfo(long ids[], int maxDepth)

[Lindenmaier, Goetz]

Hi,

I had to do some more smaller fixes to this to get it working.

The third template argument of the hash table declaration was removed in
"8214822: Move ConcurrentHashTable VALUE parameter to CONFIG". This is missing in 11, 
thus I need to specify a type for VALUE.  

Also, "8213587: Speed up CDS dump time by using resizable hashtables" 
is missing which moves primitive_hash() from resourceHash.hpp 
to globalDefinitions.hpp, so I need to include resourceHash.hpp.

Best regards,
