      Description

      This CR proposes the increase of the size of the age field for 64-bit builds of HotSpot (this includes compressed oops builds, as the object headers are 64-bit). As a result, we will also be able to increase the max tenuring threshold to higher than 15.

      This is one component of 6719225. The other component (dealing with 32-bit JVMs) we'll do in terms of 6719225.
