org.openjdk.jmh.util.Deduplicator vs threading issues

[Vladimir Sitnikov]

Hi,

Deduplicator is used in static final field of Result class, so dragons
would appear if Result objects are created concurrently.

I think it makes sense to add synchronized modifier to
org.openjdk.jmh.util.Deduplicator#dedup, so non-thread-safety issues
would not bite us in future.

Any comments?
