8344830: [BACKOUT] JDK-8341334: CDS: Parallel relocation

[shipilev]

This caused failures in higher tier testing. We are backing this out to figure test failures out without blocking testing. This also backs out related ProblemList additions: JDK-8344621. Both are clean git revert-s.

Additional testing:

• Linux x86_64 server fastdebug, runtime/cds

Backout looks good.

Thanks for doing this. We can revisit next week.

[shipilev]

Thanks. Trivial, right?

[jaikiran]

I've verified that this backout merely reverts the original changes done for the following two issues:

https://bugs.openjdk.org/browse/JDK-8341334
https://bugs.openjdk.org/browse/JDK-8344621

Looks good to me.

[shipilev]

@jaikiran, you think this is trivial, right? I need this ack to integrate without waiting for 24 hours.

[jaikiran]

@shipilev, I believe it's trivial, yes. Plus this addresses the test failures that we have noticed in our CI.

[shipilev]

OK, good. I am integrating then.
