8005082: NPG: Add specialized Metachunk sizes for reflection and 
anonymous classloaders

http://cr.openjdk.java.net/~jmasa/8005082/webrev.00/

For class metadata

1) Add a special (smaller) Metachunk size for reflection classloaders and
anonymous classloaders.
2) Use different small and medium chunk sizes for class (klass) metadata
and other (constant pool and constant pool cache) metadata.
3) Set a granularity of 8 words for humongous Metadata chunks.

Thanks.
