Delete AstNode user5 (#4638) 
This saves about 5% memory. V3AstUserAllocator is appropriate for most use
cases, performance is marginally up as we are mostly D-cache bound on
large designs.

Include systemc instead of systemc.h in model header files (#4622) (#4623) 
This may require that SystemC programs add:
using namespace sc_core;
using namespace sc_dt;

Geza Lore d330100542 Create implicit nets for inputs of gate primitives. 
Prior to this we failed to create implicit nets for inputs of gate
primitives, which is required by the standard (IEEE 1800-2017 6.10).
Note: outputs were covered due to being modeled as the LHS of
assignments, which do create implicit nets.

Geza Lore 4c0edd2efb Improve --prof-exec infrastructure and report 
Again --prof-exec have bit-rotted a little with all the recent changes
to the structure of the generated code. This patch contains a few
improvements:
- Repalce the eval/evl_loop begin/end events with generic
  section_push/section_pop events, that can be arbitrarily sprinkled
  into the generate code (so long as they are matched correctly) to
  measure various sections. The report then contains a nested profile
  of the sections, and the VCD trace shows the section names.
- Better handling of exec graphs
- Clearer overall statistics

Add prepareClone and atClone APIs for Verilated models (#3503) (#4444) 
This API is used if the user copies the process using `fork`
and similar OS-level mechanisms. The `at_clone` member function
ensures that all model-allocated resources are re-allocated, such
that the copied child process/model can simulate correctly.

A typical allocated resource is the thread pool, which every model
has its own pool.

Move suspendable detection to a separate visitor (#4208) 
This makes the implementation of the detection and propagation of the
suspendable property simpler and easier to read. More importantly, there are no
more jumps around the AST with the `visit` functions, which in some cases could
result in incorrect visitor context while in the `visit` function. See the added
test, which would cause Verilator to segfault before this patch.

In testing, verilation performance was not shown to be affected by this change.
Though there is a slight performance improvement from this patch, due to adding
one more check before refreshing class member cache.
