mem-cache: Replace block visitor with std::function

This change modifies forEachBlk tags function to accept std::function
as parameter. It also adds an anyBlk tags function that given a
condition, it iterates through the blocks and returns whether the
condition is met.

Finally, it uses forEachBlk to implement the print, computeStats and
cleanupRefs functions that also work for the FALRU class.
