RFR(M): JDK-8059036 : Implement Diagnostic Commands for heap and finalizerinfo

[Dmitry Samersoff]

Everyone,

Please review the fix:

http://cr.openjdk.java.net/~dsamersoff/JDK-8059036/webrev.01/

heap dcmd outputs the same information as SIGBREAK

finalizerinfo dcmd outputs a list of all classes in finalization queue
with count
