RFR: 8007806: Need a Throwables performance counter

[Jason Mehrens]

>From this webrev http://cr.openjdk.java.net/~nloodin/exception-tracing/webrev.01/  you are counting the number of throwables constructed.  You might want to change the name to reflect that.  I don't think anyone would want to write a spec for how many throwables are thrown given that a throwable can be wrapped, suppressed, rethrown, etc. Jason
