Description
The options `-XX:G1RSetRegionEntries` and `-XX:G1RSetSparseRegionEntries` have been obsoleted with the changes from JDK-8017163.

JDK-8017163 implements a completely new remembered set implementation in which these two options no longer apply. In this release, neither `-XX:G1RSetRegionEntries` nor `-XX:G1RSetSparseRegionEntries` have a function, and their use will trigger an obsoletion warning.
