21ac28b57a Don't build verilog twice for emulator and emulator-debug 
Since we aren't using chisel2, the output is the same either way.

fc85a3ce02 emulator,Makefile-verilator: add --output-split-cfuncs flag 
* Originally verilator will generate a large cpp file containing a large
  function, which costs about 13 min to compile. By using --output-split-cfuncs,
  this large function will be splitted into several functions in servral
  files. This will greatly improve the compile time with 'make -j'. By '-j32',
  the compile time can be reduced to about 1 min.

c61714a465 Pass MODEL variable to emulator.cc 
This enables hot-swapping of the top-level test harness by specifying
`MODEL=MyTestHarness` when building the emulator.

e51609aec0 build: support waveform debug using opensource tools 
VCS is not free. Neither is the vcd format.
Fortunately, verilator and gtkwave ARE free ... and faster too.

This patch adds targets:
	run-regression-tests-fst
	run-asm-tests-fst
... which create opensource-compatible fst waveforms for gtkwave.

ed827678ac 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.

568bfa6c50 Purge legacy HTIF things 
The SCR file is gone, too, because it was tightly coupled.  The
general concept could be revived as a module that somehow connects
to the debug module.

These failed for Andrew earlier.  While it might be paranioa, there's
really no reason to build the man pages so we might as well not bother.

571b5b2093 Prevent sbt from running multiple times in emulator 
If you have multi-target rules that don't have %s in them, make
interprets that as "run this recipe multiple times, once to produce each
target".  If you have %s in the rules, then make interprets it as "run
this recipe once to produce all targets".  We want the second one.

db9de94588 Generate and use SCR address header files 
This uses the new SCRFile changes to generate a header file containing a list
of all the SCRs in a core to remove the magic constant "63" (the HTIF clock
divider control register) and replace it with a generated number (which is
still 63).
