      Description

        Currently HeapRegionSeq only manages the HeapRegion instances corresponding to the heap's region.

        Refactor it to actually take over management of the heap region memory and the auxiliary data.

        This decreases the amount of responsibilities for G1CollectedHeap, and allows to encapsulate decisions about how memory is managed from G1CollectedHeap.

        This is a preparatory change for JDK-8038423.
