Initial implementation of generic multithreaded tracing (#2269) 
The --trace-threads option can now be used to perform tracing on a
thread separate from the main thread when using VCD tracing (with
--trace-threads 1). For FST tracing --trace-threads can be 1 or 2, and
--trace-fst --trace-threads 1 is the same a what --trace-fst-threads
used to be (which is now deprecated).

Performance numbers on SweRV EH1 CoreMark, clang 6.0.0, Intel i7-3770 @
3.40GHz, IO to ramdisk, with numactl set to schedule threads on different
physical cores. Relative speedup:

--trace     ->  --trace --trace-threads 1      +22%
--trace-fst ->  --trace-fst --trace-threads 1  +38% (as --trace-fst-thread)
--trace-fst ->  --trace-fst --trace-threads 2  +93%

Speed relative to --trace with no threaded tracing:
--trace                                 1.00 x
--trace --trace-threads 1               0.82 x
--trace-fst                             1.79 x
--trace-fst --trace-threads 1           1.23 x
--trace-fst --trace-threads 2           0.87 x

This means FST tracing with 2 extra threads is now faster than single
threaded VCD tracing, and is on par with threaded VCD tracing. You do
pay for it in total compute though as --trace-fst --trace-threads 2 uses
about 240% CPU vs 150% for --trace-fst --trace-threads 1, and 155% for
--trace --trace threads 1. Still for interactive use it should be
helpful with large designs.

Set FST timescale correctly. (#2266) 
The FST trace timescale used to be set in the constructor via
set_time_unit, but at that point we haven't normally opened the
file yet so it was just dropped. On top of that, we actually want
to use set_time_resolution... FST trace timescales now match the VCD.

Fix FST trace initial time stamp. (#2264) 
If the first dump was not at time zero, then the FST trace used
to contain the initial values as if they were set at time zero. Now
they only appear at the time the first dump call is actually made,
and hence match the VCD trace exactly.

Support IEEE time units and time precisions, #234. (#2253) 
Includes `timescale, $printtimescale, $timeformat.
VL_TIME_MULTIPLIER, VL_TIME_PRECISION, VL_TIME_UNIT have been removed
and the time precision must now match the SystemC time precision.
To get closer behavior to older versions, use e.g. --timescale-override
"1ps/1ps".

Improve tracing performance. (#2257) 
* Improve tracing performance.

Various tactics used to improve performance of both VCD and FST tracing:
- Both: Change tracing functions to templates to take variable widths as
  template parameters. For VCD, subsequently specialize these to the
  values used by Verilator. This avoids redundant instructions and hard
  to predict branches.
- Both: Check for value changes via direct pointer access into the
  previous signal value buffer. This eliminates a lot of simple pointer
  arithmetic instructions form the tracing code.
- Both: Verilator provides clean input, no need to mask out used bits.
- VCD: pre-compute identifier codes and use memory copy instead of
  re-computing them every time a code is emitted. This saves a lot of
  instructions and hard to predict branches. The added D-cache misses
  are cheaper than the removed branches/instructions.
- VCD: re-write the routines emitting the changes to be more efficient.
- FST: Use previous signal value buffer the same way as the VCD tracing
  code, and only call the FST API when a change is detected.

Performance as measured on SweRV EH1, with the pre-canned CoreMark
benchmark running from DCCM/ICCM, clang 6.0.0, Intel i7-3770 @ 3.40GHz,
and IO to ramdisk:

            +--------------+---------------+----------------------+
            | VCD          | FST           | FST separate thread  |
            | (--trace)    | (--trace-fst) | (--trace-fst-thread) |
------------+-----------------------------------------------------+
Before      |  30.2 s      | 121.1 s       |  69.8 s              |
============+==============+===============+======================+
After       |  24.7 s      |  45.7 s       |  32.4 s              |
------------+--------------+---------------+----------------------+
Speedup     |    22 %      |   256 %       |   215 %              |
------------+--------------+---------------+----------------------+
Rel. to VCD |     1 x      |  1.85 x       |  1.31 x              |
------------+--------------+---------------+----------------------+

In addition, FST trace size for the above reduced by 48%.

Allow assert disable (#2168) 
* Add +verilator+noassert flag

This allows to disable the assert check per simulation argument.

* Add AssertOn check for assert

Insert the check AssertOn to allow disabling of asserts.
Asserts can be disabled by not using the `--assert` flag or by calling
`AssertOn(false)`, or passing the "+verilator+noassert" runtime flag.
Add tests for this behavior.
Bad tests check that the assert still causes a stop.
Non bad tests check that asserts are properly disabled and cause no stop
of the simulation.

Fixes #2162.

No assign alias for unpacked public variables (#2089) 
Public variables are all emitted in the C code and unpacked arrays
arrays are sliced up for this. After inlining public unpacked array
assignments should not be alias assignments but actual assignments, so
that they are sliced and hence emitted properly.

Fixes #2073
