      Description

      In course of JMM 9 work [1], we need to conduct a few performance studies.
      This particular study needs to figure out if the access-atomicity exception for
      64-bit data types is pragmatic at this point.

      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.
