This CL is part of an effort to enable concurrent marking in MinorMC.

For this purpose we plan to reuse the IncrementalMarking class which
already implements a part of the concurrent marking code for MajorMC
(and is currently coupled with MarkCompactCollector).

We plan to parameterize IncrementalMarking with CollectorBase, which
can be either MinorMarkCompactCollector or MarkCompactCollector, in
a subsequent CL.
