RFR: 8328858: More runtime/stack/Stack0*.java fails intermittently on libgraal

[Doug Simon]

While [JDK-8328312](https://bugs.openjdk.org/browse/JDK-8328312) fixed libgraal failures on `runtime/stack/Stack011.java` and `runtime/stack/Stack012.java`, other `runtime/stack/Stack0*` tests still fail:

This PR mitigates such failures by bumping `depthToTry` by at least an order of magnitude.

The right long term fix for these tests is probably [JDK-8328859](https://bugs.openjdk.org/browse/JDK-8328859).
