6784849: par compact - old/new address assertions are too strong

	Change the assertions that check before compaction/after
	compaction addresses to handle the case when data is moved
	from a space at lower addresses to a different space at higher
	addresses.  Currently, this only occurs with the survivor
	spaces, when to_space < from_space.

6786188: par compact - "SplitALot" stress mode should fill to_space

	Update ParallelOldGCSplitALot so compaction occasionally sees
	objects in both from_space and to_space.  This helped diagnose

Neither of the above affect any product code.
