> [JDK-8298614](https://bugs.openjdk.org/browse/JDK-8298614) enabled writing the archived heap region with SerialGC and ParallelGC, but archives written with XX:-UseCompressedOops can't be loaded at runtime. This patch enables heap loading for SerialGC and ParallelGC as well as EpsilonGC and Shenandoah since they were enabled in [JDK-8341913](https://bugs.openjdk.org/browse/JDK-8341913). Related tests were updated to check for the new conditions. Verified with tier 1-5 tests.
