Fix memtester to use functional access, fix cache to work functionally now that we could test it.

src/cpu/memtest/memtest.cc:
    Fix memtest to do functional accesses
src/mem/cache/cache_impl.hh:
    Fix cache to handle functional accesses properly based on memtester changes
    Still need to fix functional accesses in timing mode now that the memtester can test it.
