mem: Handful extra features for BasePrefetcher

Some common functionality added to the base prefetcher, mainly dealing with
extracting the block addres, page address, block index inside the page and
some other information that can be inferred from the block address. This is
used for some prefetching algorithms, and having the methods in the base,
as well as the block size and other information is the sensible way.
