0368b6db6b ahb: replace defective crossbar with a functional one 
The previous crossbar had the following bugs:
  1. a bursting master could be preempted
     the AHB-lite spec requires a slave receive the entire burst

  2. a waited master could be replaced
     the AHB-lite spec requires haddr/etc to remain unchanged

  3. hmastlock did no ensure exclusive access
     atomic operations could be pre-empted

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.

742c05d6a7 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).

3fe00ce32a Update README.md 
- Removed instruction to checkout riscv-tests (as they are now globally installed when building the riscv-tools).
- Clarified the riscv-tools set-up information to clarify that the rocket-chip/riscv-tools is the version to build.
