RFR (S): JDK-8027440: DefNew does not log heap change information when a promotion failure occurs

[Bengt Rutisson]

Hi all,

Can I have a couple of reviews for this small change?

http://cr.openjdk.java.net/~brutisso/8027440/webrev.00/

https://bugs.openjdk.java.net/browse/JDK-8027440

DefNew was not printing the heap change information when a promotion 
failure occured. Before this change the logging for a DefNew collection 
that got promotion failure looked like this:

[GC (Allocation Failure) , 0.0543440 secs]

After my change it looks like:

[GC (Allocation Failure)  81920K->120831K(120832K), 0.0620180 secs]

Thanks,
Bengt
