RFR (XS): Forward port of 8065331: Add trace events for failed allocations

[Marcus Larsson]

Hi,

Please review the following patch to forward port the JEP-242 event to 
JDK9. The patch was originally reviewed in April/March [1], but was only 
integrated in 8u60. The original patch no longer applies cleanly to 9, 
due to directory restructuring and changes to includes, so I need a 
quick re-review for this.

The new patch has updated #includes for the new directory structure but 
should otherwise be identical to the previous patch.

Thanks,
Marcus
