Added support for logic memory in the IFU and LSU. This disables the bus interface. Peripherals do not work. Also requires using testbench-harvard.sv. I hope to merge this testbench with the main testbench.sv soon.

Fixed bug with interlock fsm. The interlock fsm should suppress bus and cache requests by the cpu
...
only at the start of a request. Pending interrupt was used to start one of these suppressions;
however because of the way the cache's fsm was separated from the bus fsm, the cache now made requests
to the bus fsm. On a miss with write back, the inital fetch is handled correctly. However if an
interrupt becam pending then the the next request (eviction) made by the cache was also suppressed.
This keeps the d cache fsm stuck in the STATE_MISS_EVICT_DIRTY state as it think it has made a request
to the bus fsm, but the pending interrupt ignored the request.
The solution is to modify how cpu requests are suppressed. Instead of relying on pending interrupt
it is better to use interrupt which will be disabled if the dcache is currently processing the evict.
