Previously there was one per bus, which caused some coherence problems
when more than one decided to respond. Now there is just one on
the main memory bus. The default bus responder on all other buses
is now the downstream cache's cpu_side port. Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

Caveats:
- Even though memtest is ISA-independent, it will only
run for the Alpha builds, since there's no way to specify
ISA-independent reference files and I didn't want to commit
3 copies since I'm not sure we want to run it for all the
different ISAs anyway.
- Reference outputs were generated on my laptop,
so performance numbers will be low compared to zizzer.
