Rework the memory ops to use a cache higherarchy

 - Implement an LFU cache with latencies
 - Reimplement the memory write function to access the cache
 - Reimplement the memory read function to access the cache
Add a helper for making processors

Because a processor now contains all this book keeping with respect to
the cache higherarchy, add a helper function which can upgrade the
traditional inline state literal to a cache higherarchy armed map.
Rework instrs->state to do the right thing with respect to the cache

instrs->state now builds a cache higherarchy silently.
