Please review this small fix for some CDS tests that fail on machines with a lot of RAM.

The reason is the max heap size setting is used only when the CDS archive is dumped. As a result, when we try to use the CDS archive, the VM ergonomics may use a different oop encoding, and the CDS archive becomes unuseable.

The fix is to use the same -Xmx when both dumping and using the CDS archive.
