It seems only used in one area of Shenandoah code, where it seems like they should be using PTR_FORMAT, except they are trying to output fewer leading zeros.  I'm somewhat inclined to say this doesn't belong in globalDefinitions.hpp at all; if they have specialized printing desirements they can define whatever they want themselves.

I've moved this to Shenandoah now.
