RFR: 8255072: [TESTBUG] com/sun/jdi/EATests.java should not fail if expected VMOutOfMemoryException is not thrown [v3]

[Richard Reingruber]

> The following test cases try to provoke VMOutOfMemoryException during object reallocation:
> 
> EAPopFrameNotInlinedReallocFailure
> EAPopInlinedMethodWithScalarReplacedObjectsReallocFailure
> EAForceEarlyReturnOfInlinedMethodWithScalarReplacedObjectsReallocFailure
> 
> This is not 100% reliable therefore it should not be treated as test failure if no oom was raised.

Richard Reingruber has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains four additional commits since the last revision:

 - Skip test cases expecting OOMEs if running with ZGC.
 - Merge branch 'master' into JDK-8255072-eatests-oom-not-thrown
 - Make OOME more reliable and skip test cases if it is not expected because scalar replacement is disabled
 - 8255072: [TESTBUG] com/sun/jdi/EATests.java should not fail if expected VMOutOfMemoryException is not thrown
