    Description

      Metaspace verifications (controlled by VerifyMetaspace) are usually switched off because they are too expensive.

      Modify them to make them cheaper and more thorough. Add a switch to control verification interval, and in debug builds set it to a reasonable default which is not too expensive but still runs at least sometimes (as an orientation, runtime/SelectionTests should not slow down noticably).
