c069e66056 Modify the RoCC interface to include status in the command queue. (#41) 
This addresses a bug in which changes in mstatus could
propagate to RoCCs before their time. Existing RoCCs that use
the status port will need to be modified to match this change.

This addresses the first half of #40.

4af6313288 TraceGen: Lookup -> MuxLookup 
A recent commit to tracegen.scala introduced a call to BitPat() which
seems to mess up the subsequent call to Lookup().  (This function
seems undocumented so I'm not sure what's going on.)  As a fix, I've
removed the call to BitPat() and replaced Lookup() with MuxLookup().
