RFR (X): JDK-8078613: HAS_BEEN_MOVED has been moved

[Bengt Rutisson]

Hi everyone,

A small Friday afternoon cleanup:

https://bugs.openjdk.java.net/browse/JDK-8078613
http://cr.openjdk.java.net/~brutisso/8078613/webrev.00/

The define HAS_BEEN_MOVED is unused, so it must have been moved away at 
some point in time. The definition dates back to the initial load of the 
mercurial repo, but it has never been in use.

The "FIX ME FIX ME" comment a few lines up in psPromotionManager.hpp 
kind of looks like another simple cleanup in this file, but I'll leave 
that for another time or for someone else to sort out.

Thanks,
Bengt
