      Description

      Vector box elimination can leave non-counted loops without safepoints.

      It happens when VectorBox isn't used and, hence, eliminated, but all other safepoints were removed before in favor of that node.

      C2 should replace VectorBox with a SafePoint node as part of elimination process.
