RFR (XS) 8205702: assert(UseCompressedClassPointers) failed in universe.hpp

Hi Coleen,

This looks good.

Should we also disable UseSharedSpaces at runtime for ZGC in case an archive was dumped using a different GC algorithm? I ran into tmpfs error when trying to run with ZGC, so I couldn’t double check for that case...

Thanks,
Jiangli
