I did consider when working on `VarHandle` tests recently, but figured this split penalizes the total CPU time quite significantly. Given that these tests run in `tier1`, when there is significant external parallelism already, it seems to waste time for little gain.

Please run `java/lang/invoke/VarHandles` and `tier1` with `time` to ballpark the time changes on your test systems.
