Sync from jdk8/jdk8 to ppc-aix-port/stage is skipped this week

[Vladimir Kozlov]

I want to skip the sync this week. I did JPRT testing and several jdk 
and Hotspot tests are failed because of known bugs. Fixes for these bugs 
will be promoted next week.

The only interesting change in the merge is 8016697: Use stubs to 
implement safefetch.

Thanks,
Vladimir
