I would like to add a test for JDK-8269661. 

Currently, JDK-8269661 only affects Shenandoah GC, as it is the only GC supports object pinning and string deduplication.

- [x] new test passes with JDK-8269661, fails after backout JDK-8269661 fix.


Commit messages:
 - Disable compact string
 - Merge branch 'master' into string_critical_dedup
 - update test
 - v2
 - v0
