f790f34fe3 Make Bus::findPort() a little more useful. 
Move check for loops outside, since half the call sites
end up working around it anyway.  Return integer port ID
instead of port object pointer.

6babda7123 Fix up a few statistics problems. 
Stats pretty much line up with old code, except:
- bug in old code included L1 latency in L2 miss time, making it too high
- UniCoherence did cache-to-cache transfers even from non-owner caches,
so occasionally the icache would get a block from the dcache not the L2
- L2 can now receive ReadExReq from L1 since L1s have coherence
