To be useful for MPS, we would probably need sections that can be loaded
to different/non-contiguous memory blocks that are allocated by MPS.
(One section per MPS pool).  That would require some work on the
pdumper.

It's less relevant for MPS because MPS is incremental and generational
and so pure objects contribute much less to the average GC pause time.
