JDK-8267697 - [lworld] [lw3] VM crashes during heap dump if Java heap contains flat arrays
Description
HeapDumper creates separate HPROF_GC_INSTANCE_DUMP record for each inlined object.
But if the object contains "default" value (all zeroes) it can be linked to "default" object of the class (and then dumper does not need to dump its fields including fields of Q-type)
