Perform VCD tracing in parallel when using --threads ( #3449 )
...
VCD tracing is now parallelized using the same thread pool as the model.
We achieve this by breaking the top level trace functions into multiple
top level functions (as many as --threads), and after emitting the time
stamp to the VCD file on the main thread, we execute the tracing
functions in parallel on the same thread pool as the model (which we
pass to the trace file during registration), tracing into a secondary
per thread buffer. The main thread will then stitch (memcpy) the buffers
together into the output file.
This makes the `--trace-threads` option redundant with `--trace`, which
now only affects `--trace-fst`. FST tracing uses the previous offloading
scheme.
This obviously helps a lot in VCD tracing performance, and I have seen
better than Amdahl speedup, namely I get 3.9x on XiangShan 4T (2.7x on
OpenTitan 4T).

Improve run-time profiling
...
The --prof-threads option has been split into two independent options:
1. --prof-exec, for collecting verilator_gantt and other execution
related profiling data, and
2. --prof-pgo, for collecting data needed for PGO
The implementation of execution profiling is extricated from
VlThreadPool and is now a separate class VlExecutionProfiler. This means
--prof-exec can now be used for single-threaded models (though it does
not measure a lot of things just yet). For consistency VerilatedProfiler
is renamed VlPgoProfiler. Both VlExecutionProfiler and VlPgoProfiler are
in verilated_profiler.{h/cpp}, but can be used completely independently.
Also re-worked the execution profile format so it now only emits events
without holding onto any temporaries. This is in preparation for some
future optimizations that would be hindered by the introduction of function
locals via AstText.
Also removed the Barrier event. Clearing the profile buffers is not
notably more expensive as the profiling records are trivially
destructible.

Reduce .rodata footprint of trace initialization ( #3250 )
...
Trace initialization (tracep->decl* functions) used to explicitly pass
the complete hierarchical names of signals as string constants. This
contains a lot of redundancy (path prefixes), does not scale well with
large designs and resulted in .rodata sections (the string constants) in
ELF executables being extremely large.
This patch changes the API of trace initialization that allows pushing
and popping name prefixes as we walk the hierarchy tree, which are
prepended to declared signal names at run-time during trace
initialization. This in turn allows us to emit repeat path/name
components only once, effectively removing all duplicate path prefixes.
On SweRV EH1 this reduces the .rodata section in a --trace build by 94%.
Additionally, trace declarations are now emitted in lexical order by
hierarchical signal names, and the top level trace initialization
function respects --output-split-ctrace.
