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.

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.
