Request for Review (s) - 8014862:Add fast Metasapce capacity and used per MetadataType

[Jon Masamitsu]

I've updated the repository for review comments (thanks Erik and
Stefan).  New webrev is

http://cr.openjdk.java.net/~jmasa/8014862/webrev.01/

To check the format of the warning for assert on the decrement the
of used and capacity, added (temporary) debug code to print
out the message of the warning.
