RFR: 8036701: Add trace event when a metaspace throws out of memory error

[Erik Helin]

Based on a discussion with Jon Masamitsu and StefanK, I've decided to 
change metadata_type_name to return a slightly more user-friendly value.

Please see new webrev at:
http://cr.openjdk.java.net/~ehelin/8036699/webrev.02/

Incremental webrev:

Thanks,
Erik
