3. Full GC with memory pressure - weakly and softly referenced non-humongous and humongous objects are collected.
4. CMC - weakly referenced non-humongous objects are collected, other objects are not collected since weak references
from Young Gen is handled as strong during CMC.
5. CMC_NO_SURV_ROOTS - weakly referenced non-humongous and humongous objects are collected, softly referenced
non-humongous and humongous objects are not collected since we make 2 Young GC to promote all
weak references to Old Gen.
The test gets gc type as a command line argument.
Then the test allocates object graph in heap (currently testing scenarios are pre-generated and stored in
TestcaseData.getPregeneratedTestcases()) with TestObjectGraphAfterGC::allocateObjectGraph.
