d4c94c6566 Chisel3 has different Vec semantics 
Vec(a, b) := c doesn't modify a and b in chisel3.

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.

6d7cc37e87 Specify some uninferrable widths 
It's really scary that Chisel2 passed this stuff.

0686bdbe28 Avoid cross-module references 
You can't instantiate a Vec in one module and use it in another.
An idiosyncrasy of the Chisel2 implementation let this one slip by.
In this case, it's just a matter of using def instead of val.

f8ec6d6393 Chisel3 compatibility: use BitPat for don't-cares 
Also, call the UInt factory instead of the Bits one, for good measure.
