RFR: 8340105: Expose BitMap::print_on in release builds

[Aleksey Shipilev]

A small quality of life improvement.  This irritates me often enough when I am looking at various bitmaps in release builds. BitMap::print_on is not available in release builds, and bitmaps in debug builds are sometimes different than the ones in release builds. This often forces me to do additional hack to expose it. I think it should just be available in release builds to begin with.
