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.

Pipeline D$->I$ control paths

These stretch the miss latency by a cycle in exchange for slack.
The current implementation also adds a cycle to mul/div latency,
which can be worked around for more hardware (possibly gated by
the FastMulDiv option).
