There are already too many classes related to BFI, so I am not a fan of introducing another LazyBFI.

I suggest just making BFI lazy itself (when getBlockFreq() is first called ...). In fact  I think the laziness handling should be in BlocFrequencyInfoImpl class. By so doing, MBFI can get the laziness automatically as well.
