RFR: Adding evacuation failed tracing event

[Jesper Wilhelmsson]

Hi,

I'm looking for a couple of reviews for this change.

The change is to add evacuation failed tracing events to G1. Since the 
evacuation failed is very similar to a regular promotion failed in other young 
GCs, these events share most of the code.

I have split the change into two parts:


1) JDK-8009992: Prepare tracing of promotion failed for integration of 
evacuation failed

Webrev: http://cr.openjdk.java.net/~jwilhelm/8009992/webrev/

This part refactors the promotion failed code to use a generic copy failed class 
which is used as the base for the promotion failed handling.


2) JDK-8008916: G1: Evacuation failed tracing event

Webrev: http://cr.openjdk.java.net/~jwilhelm/8008916/webrev/

This part adds the new event for G1 evacuation failed.


Thanks,
/Jesper
