3cc236e9c4 By default, use same TileLink width everywhere 
When there's no L2 with a wide interface, having wider TileLink
is only disadvantageous.

abb0e2921b return non-zero exit codes when an assertion fires 
This ensures that assertion failures, which currently print a message to
the console but return a successful exit code, now will cause non-zero
exit code. This is meant to help automated tools like travis and
buildbot do a better job at catching assertions.
This impacts the various run-* targets in the simulation
directories.

c5838dd9b3 Fix narrow read/write behavior for AXI converters and fix L2 bugs 
Until recently, we were assuming that the data channel in AXI was always
right-justified. However, for narrow writes, the data must actually be
aligned within the byte lanes. This commit changes some of the
converters in order to fix this issue.

There was a bug in the L2 cache in which a merged get request was
causing the tracker to read the old data from the data array,
overwriting the updated data acquired from outer memory. Changed it so
that pending_reads is no longer set if the data in the buffer is already
valid.

There was a bug in the PortedTileLinkCrossbar. The new GrantFromSrc and
FinishToDst types used client_id for routing to managers. This caused
bits to get cut off, which meant the Finish messages could not be routed
correctly. Changed to use manager_id instead.

ad93e0226d 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
