52fc34a138 Chisel3: bulk connect is not commutative 
We haven't decided if this is a FIRRTL limitation that we should relax,
or a backwards incompatibility we're forced to live with.  Should make
for lively debate.

6a9390c50e Avoid spurious D$ assertion failures 
For the Rocket pipeline, this fix is needless and the problem is that the

for other plausible use cases where physical and virtual accesses are
intermixed.
