RFR: 8376402: Dependencies::print_statistics() and AbstractClassHierarchyWalker::print_statistics() are not called from PRODUCT code [v2]

[Matthias Baesken]

> Dependencies::print_statistics() and AbstractClassHierarchyWalker::print_statistics() are not called from PRODUCT code but seems they still end up in the product build JVM, at least when using standard build settings.
> (This can be observed when enabling link time gc and verbose info printing - in this case the methods are eliminated).
> 
> linuxx86_64
> product build without those methods
> 
> ls -alL images/jdk/lib/server/libjvm.so
> size 2.859.5144
> 
> 
> unchanged product build :
> 
> ls -alL images/jdk/lib/server/libjvm.so
> size 2.859.9464
> 
> 
> (so we see a little size difference)
