Finally fixed the lru bug. It was actually a flush bug all along. At the end of flush writeback FlushAdr is incremented so clearly the dirty bit then clears the wrong set. Must either take an additional cycle to clear dirty and then change the address or clear the dirty bit before the cache bus acknowledgment. Changed it to clear at begining of that line's writeback before actually writting back.

At long last found the subtle bug in the LRU.
...
Since the LRU memory is two ports, 1 read and 1 write, a write in cycle 1 to address x should not
forward data to a read from address y in cycle 2.
A read form address x in cycle 2 would still require forwarding.

I found the issue with the cache changes. FlushW is not asserted for all TrapM. Ecall and Ebreak don't flush the W stage. However the ifu's bus controllable must disable the BusRW for all traps.

Oups found a bug with my cache changes. I took TrapM out of the logic path for selecting the cache's address CAdr (previously RAdr) to improve the critical path. This is fine for the dcache because both the E and M stages are flushed. However for the ICache only F is flushed. PCNextF is valid and points to XTVEC so the cache must take NextAdr rather than PAdr as CAdr.

hazard was not a straight forward merge. I changed the way the LSU and IFU generate IFUStallF and LSUStallM. They need to be suppressed by TrapM now.

Removed TrapM from the LSU and IFU. TrapM is replaced with FlushW for both. (Don't like this for the IFU).
...
FlushW prevents writting the cache, dtim, and bus state. FlushW still gates HTRANS.
FlushW does not impact the mealy outputs of the cache and bus FSMs and hazard is updated to
not stall W if we get a trap.
