90a797e71a Make MemTraceDriver generate word-sized requests 
Try to model the core's behavior which accesses cache in word granularity.  This
also simplifies the coalescer design as coalescer no longer needs to uncoalesce
response data chunk into single bytes (and therefore fewer muxes).

db06bda674 Count req/resp lines and bytes to coalescer and test match 
Note total bytes in requests and responses (i.e. traffic) don't
need to match because of redundant requests to the same address may get
coalesced.

de6d6eee1a Fix request shift queue not enqueuing when empty 
The queue was enabling shifting of the registers whenever deq.ready
was 1, even when the queue was empty.  This caused `wen` to disable
writing enq.bits to any of the entries in the queue.  Fixed by setting
`shift` to 0 when queue is empty.

41d520a991 Log both request and response in trace logger 
Inside DPI code, have a vector of unique_ptrs that act as handles to multiple
different trace logger instances.  Each logger instance is instantiated in a
single instance of the Verilog module, and multiple of these Verilog modules may
be instantiated in the Chisel module (see simReq and simResp in MemTraceLogger).

8e6a5f4bce Fix address & data handling in memtrace driver and logger 
* TileLink doesn't alter the `address` field from what we originally used in the
  Get/Put call.
* Same goes for the `data` field.
* The only thing TL generates by itself is `mask`.  This means we have to align
  data to the beatBytes boundary ourselves when Putting, and also taking
  the right sublanes using the mask when Getting.

b53711965e Connect TL edge data to SimMemTraceLogger 
TODO: since TileLink rounds all address down to a multiple of its beat
size (8 in the current code), we can't directly compare the memory trace
input to its output.  Need to take masks into account.

452cc40eb7 Make MemTraceLogger pass-through node 
Instead of making MemTraceLogger a TL slave, make it an IdentityNode
that simply snoops on the TL edges and generates logs.
We can attach a TLRAM at the downstream to actually get response back,
rather than MemTraceLogger simply absorbing all requests.
