Hi,

I'm looking for a couple of reviews for the promotion failed tracing event, now implemented for ParNew and Serial GC.

I have replaced the existing counters and booleans with a PromotionFailedInfo object and uses that throughout, so now promotion failed reporting (through the tracing framework) looks the same and reports the same data for all young collectors.

I have added two new fields to the promotion failed event: firstSize as reported by ParNew logging, and smallestSize which is the smallest object size that failed to promote.

Webrew: http://cr.openjdk.java.net/~jwilhelm/8008790

Testing: Passes JPRT and the existing promotion failed tests with all 
collectors.

Thanks,
/Jesper
