I notice that both `clear_MemRegion` and `clear_MemRegion` of the class `CardTable` use the method `memset`. (And many other places use `memset` too.) In my opinion, such common problem should be discussed in another issue. After coming to a conclusion, we can change all of them one time. @kimbarrett @albertnetymk what is your opinion?
