ClockDivider2: fix launch alignment of clocks (vcs) Doing this in Chisel leads to non-determinism due to shitty Verilog ordering semantis. Using an '=' ensures that all of the clock posedges fire before concurrent register updates. See "Gotcha 29: Sequential logic that requires blocking assignments" in "Verilog and SystemVerilog Gotchas" by Stuart Sutherland, Don Mills.

Write test harness in Chisel This is an unavoidably invasive commit, because it affects the unit tests (which formerly exited using stop()), the test harness Verilog generator (since it is no longer necessary), and the DRAM model (since it is no longer connected). However, this should substantially reduce the effort of building test harnesses in the future, since manual or semi-automatic Verilog writing should no longer be necessary. Furthermore, there is now very little duplication of effort between the Verilator and VCS test harnesses. This commit removes support for DRAMsim, which is a bit of an unfortunate consequence. The main blocker is the lack of Verilog parameterization for BlackBox. It would be straightforward to revive DRAMsim once support for that feature is added to Chisel and FIRRTL. But that might not even be necessary, as we move towards synthesizable DRAM models and FAME-1 transformations.

Add in a SimJTAG to connect to OpenOCD's remote-bitbang interface. This is simpler than JTAGVPI and is supported better by Verilor. It is also the same thing Spike uses.
