- Remove _ENUM_END, so -Wswitch does not demand it's covered. Use the
new NUM_TYPES constexpr member instead.
- Remove 'at' prefix. This seems historical and is not particularly useful.
- Fix some cppcheck warts while at it
Added cppcheck-suppressions.txt in the repo root. You can add new
patterns in there instead of having to parse the XML output.
Also configure to add the -D__GNUC__ preprocessor macro, which makes it
understand UASSERT (it understands the 'noreturn' function attribute).
Added some case by case specific suppressions and fixed up other code,
especially in V3Ast*h and V3Dfg*.h, including code generated by astgen
that had some no-ops that irks cppcheck.
One thing it does not seem to like is `const` class members with default
initializers in the class. It will assume that's always the value, even
if overridden in the constructor. We had few so removed them.
With that a lot of files in `src/` are now clean or only have a handful
of issues. Therefore, I have also deleted cppcheck_filtered, and made it
produce human readable output straight to the terminal.
Regarding cleaning up the reported nits, I kind of got bored after
V3[A-E] so pausing here. Apologies for the merge conflicts.
Tested with cppcheck 2.13.0
According to IEEE 1800-2023 12.7.3, the loop creates an implicit block
around it, containing declarations of the loop variables with automatic
lifetime.
No functional change intended.

Static variables of functions are created in the function. When blocks
in a function use identical names for static variables, we need to name
those variables properly.
Before this patch, calling tasks directly under forks would result in each
statement of these tasks being executed concurrently. This was due to Verilator
inlining tasks most of the time. Such inlined tasks' statements would simply
replace the original call, and there would be no indication that these used to
be grouped together. Ultimately resulting in `V3Timing` treating each statement
as a separate process.
The solution is simply to wrap each fork sub-statement in a begin in `V3Begin`
(except for the ones that are begins, as that would be pointless). `V3Begin` is
already aware of forks, and is supposed to avoid issues like this one, so it
seems like a natural fit. This also protects us from similar bugs, i.e. if some
statement gets replaced or expanded into multiple statements.

- Rename `--dump-treei` option to `--dumpi-tree`, which itself is now a
special case of `--dumpi-<tag>` where tag can be a magic word, or a
filename
- Control dumping via static `dump*()` functions, analogous to `debug()`
- Make dumping independent of the value of `debug()` (so dumping always
works even without the debug flag)
- Add separate `--dumpi-graph` for dumping V3Graphs, which is again a
special case of `--dumpi-<tag>`
- Alias `--dump-<tag>` to `--dumpi-<tag> 3` as before
Introduce the @astgen directives parsed by astgen, currently used for
the generation child node (operand) accessors. Please see the updated
internal documentation for details.

Generate type specific static overloads of Ast<Node>::addNext, which
return the correct sub-type of the 'this' they were invoked on.
Also remove AstNode::addNextNull, which is now only used in the parser,
implement in verilog.y directly as a template function.
