RFR: 8255072: [TESTBUG] com/sun/jdi/EATests.java should not fail if expected VMOutOfMemoryException is not thrown [v5]

[Richard Reingruber]

> The following test cases try to provoke VMOutOfMemoryException during object reallocation because of JVMTI PopFrame / ForceEarlyReturn:
> 
> EAPopFrameNotInlinedReallocFailure
> EAPopInlinedMethodWithScalarReplacedObjectsReallocFailure
> EAForceEarlyReturnOfInlinedMethodWithScalarReplacedObjectsReallocFailure
> 
> For ZGC (so far) this is not 100% reliable.
> 
> Just ignoring the runs where the expected OOME was not raised was not accepted.
> 
> Summary of the now accepted solution:
> 
> - The 3 problematic test cases are skipped if ZGC is selected.
> 
> - They are also skipped if no OOME during object reallocation can be expected because allocations are not eliminated.
> 
> - In consumeAllMemory, as a last step, empty LinkedList nodes are created without long array to fill up small blocks of free memory.
> 
> - EATests.java is removed from the problem list for ZGC.
