      After JDK-8029075 the new string dedup unlink phase has been added to the unlink_string_and_symbol_table() method as a separate parallel task.

      However this adds an additional unnecessary setup/teardown of the worker threads, taking a few ms on a large machine.

      Merge the G1StringSymbolTableUnlinkTask with the G1StringDedupUnlinkOrOopsDoTask so that the latter work is done within the same "task".
