RFR: 8263915: runtime/cds/appcds/MismatchedPathTriggerMemoryRelease.java fails when UseCompressedClassPointers is off [v2]

[Jie Fu]

> Hi all,
> 
> runtime/cds/appcds/MismatchedPathTriggerMemoryRelease.java fails on x86_32 due to failure of this check [1].
> However, this check will always fail if UseCompressedClassPointers=0 [2] (e.g., on x86_32) since the class_space_rs remains unreserved.
> It would be better to fix it.
> 
> Thanks.
> Best regards,
> Jie
