An exploded JDK cannot be used with either -Xshare:on or -Xshare:auto. That causes tests like runtime/CompressedOops/CompressedCPUSpecificClassSpaceReservation.java to fail when running on an exploded JDK.

Since an exploded JDK cannot use CDS, we should - for the purposes of tests - treat it as if CDS had not been included.
