9d7086067c Rework serial/parallel build mode 
Instead of __ALLfast.cpp and __ALLslow.cpp, we now create only a single
__ALL.cpp and compile it with OPT_FAST, this speeds up small builds
where the C compiler does not dominate. A separate patch will follow
turning VM_PARALLEL_BUILDS on by default at a certain size.

Given this change to the build there is now no point in emitting both
fast and slow routines into the same .cpp file when --output-split is
not set as they will be just included in the same __ALL.cpp file. To
keep things simpler and the output easier to comprehend, V3EmitC has
also been changed to always emit the fast and slow files separately.

Also change verilated.mk to apply OPT_SLOW to all slow files, not just
ones called *__Slow.cpp. This change in particular ensures __Syms.cpp
is build as slow.

Part of #2360.

900c023bb5 Refactor trace implementation to allow experimentation 
The main goal of this patch is to enable splitting the full and
incremental tracing functions into multiple functions, which can then be
run in parallel at a later stage. It also simplifies further
experimentation as all of the interesting trace code construction now
happens in V3Trace. No functional change is intended by this patch, but
there are some implementation changes in the generated code.

Highlights:
- Pass symbol table directly to trace callbacks for simplicity.
- A new traceRegister function is generated which adds each trace
function as an individual callback, which means we can have multiple
callbacks for each trace function type.
- A new traceCleanup function is generated which clears the activity
flags, as the trace callbacks might be implemented as multiple functions.
- Re-worked sub-function handling so there is no separate sub-function
for each trace activity class. Sub-functions are generate when required
by splitting.
- traceFull/traceChg are now created in V3Trace rather than V3TraceDecl,
this requires carrying the trace value tree in TraceDecl until it
reaches V3Trace where the TraceInc nodes are created (previously a
TraceInc was also created in V3TraceDecl which carries the value).

Use SIMD intrinsics to render VCD traces (#2289) 
Use SIMD intrinsics to render VCD traces.

I have measured 10-40% single threaded performance increase with VCD
tracing on SweRV EH1 and lowRISC Ibex using SSE2 intrinsics to render
the trace. Also helps a tiny bit with FST, but now almost all of the FST
overhead is in the FST library.

I have reworked the tracing routines to use more precisely sized
arguments. The nice thing about this is that the performance without the
intrinsics is pretty much the same as it was before, as we do at most 2x
as much work as necessary, but in exchange there are no data dependent
branches at all.

b79ef672e1 Various minor optimizations of VCD trace routines 
- Change templated trace routines to branch table.

Removed templating from trace chgBus and fullBus and replaced them with
a branch table like the other there is a very small (< 1%) penalty for
this on SwerRV EH1 CoreMark, but this is less than the variability of
disk IO so it's worth it to keep the code simpler and smaller.

- Prefetch VCD suffix buffer at the top of emit*

- Increase ILP in VCD emit* routines

- Use a 64-bit unaligned store to emit the VCD suffix (on x86 only)

The performance difference with these is very small, but the changes
hopefully make this code more performance-portable across various
micro-architectures.

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.

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%.

When using the __ALL*.cpp based single compile mode (i.e.: without

__Allsup.cpp, which was compiled with OPT_SLOW, severely harming tracing

Fix FST tracing performance by removing std::map from hot path. (#2244) 
This patch eliminates a major piece of inefficiency in FST tracing
support, by using an array to lookup fstHandle values corresponding
to trace codes, instead of a tree based std::map. With this change, FST
tracing is now only about 3x slower than VCD tracing. We do require
more memory to store the symbol lookup table, but the size of that is
still small, for the speed benefit.

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.

* Add description for single test execution

Without this description it is not obvious how to run a single test from
the regression test suite.

045ff25f80 Support vpiModule, bug1469. 
Add very basic support for vpiModule. Basically it allows to traverse
the module tree to find a variable etc. It does not support more than
vpi_iterate and vpi_scan for vpiModule along basic operations like
vpi_get_str on vpiModule.

The support is added non-intrusively to non-VPI verilator runs. It
essentially:

 - Tracks the creation of cell instances and keeps them alive until
   the emit phase. They are there converted to scopes if modules.

 - Emits empty (don't add anything during construction)
   VerilatedScopes for all inlined modules, only for those inlined
   modules that are on the hierarchical path to public variables.

 - Adds VerilatedHierarchy as abstraction to structure of the
   scopes. It is only created for VPI designs. It allows to traverse
   the hierarchy from the top (NULL).
