      Description

      In the wake of JMM9 overhaul work [1], we need to conduct a few performance studies.
      One of these studies include figuring out if enforcing the safe construction of *all* objects,
      regardless of whether they contain the final fields affects performance in any sensible way.

      This issue tracks the experimental VM work for that; it can be also merged to master,
      if we want to simplify performance study freeing everyone from building the patched VM.
