Changes to prepare for switch to TileLink interconnect
...
We are planning on switching to a TileLink interconnect throughout and
convert to AXI only on the very edge. Therefore, we need to get rid of
all the existing AXI masters other than the TileLink to AXI converter.
* Get rid of DMA engine for now
* Connect RTC to TileLink interconnect instead of AXI interconnect

separate btb response mask from the frontend mask
...
It is now the job of the pipeline to monitor the frontend's valid mask (of
instructions) and the BTB's suggested valid mask (based on the prediction it
makes). Some processors may want to ignore or override the BTB's prediction and
thus can supply their own instruction mask.

Preliminary Chisel 3 Support

Use Chisel 3 to build verilog on Travis
...
Chisel 3 can't build the C++ emulator, so we currently can't have direct
support for testing RocketChip. We can at least test to see if the
Verilog builds when run through Chisel 3, which this patch does.

This allows users to specify if they want to build RocketChip against

submodule pointers directly to avoid a fork of upstream.

change WriteMaskedPutBlockRegression for better bug detection
...
Instead of sending puts back-to-back, separate the two puts with a get.
Also, stall a bit between each transaction. This makes sure the puts and
intermediate get are sent to the same transactor, which will cause the
data buffer to get overwritten between the two puts.

Trace generator: updates and additions to the scripts directory.
...
(1) Introduce tracegen.py, a script that invokes the emulator (built
with TraceGenConfig), sending a SIGTERM once all cores are finished.
(2) Update toaxe.py to gather some statistics about the trace.
(3) Introduce tracestats.py, which displays the stats in a useful way.
(4) Introduce tracegen+check.py, a top-level script that generates
traces, checks them, and emits stats. If this commit is pulled, it
should be done after pulling my latest groundtest commit.

Updates to the trace-generator: (1) Don't terminate via HTIF exit, which can cause other, unfinished, cores to be cut short. Instead emit FINISHED messsages allowing an external process to send a SIGTERM to the emulator once all cores have finished. (2) Add some support for greater address variation without having to recompile, disabled by default. (3) Generate atomic, LR/SC, and fence operations by default in addition to plain loads and stores. These changes require newer versions of files in the rocket-chip/scripts directory. I will submit a pull request for those too.
