Geza Lore 65e08f4dbf Make all expressions derive from AstNodeExpr (#3721).
Apart from the representational changes below, this patch renames
AstNodeMath to AstNodeExpr, and AstCMath to AstCExpr.

Now every expression (i.e.: those AstNodes that represent a [possibly
void] value, with value being interpreted in a very general sense) has
AstNodeExpr as a super class. This necessitates the introduction of an
AstStmtExpr, which represents an expression in statement position, e.g :
'foo();' would be represented as AstStmtExpr(AstCCall(foo)). In exchange
we can get rid of isStatement() in AstNodeStmt, which now really always
represent a statement

Peak memory consumption and verilation speed are not measurably changed.

Partial step towards #3420

Add custom memory management for verilated classes (#3595)
This change introduces a custom reference-counting pointer class that
allows creating such pointers from 'this'. This lets us keep the
receiver object around even if all references to it outside of a class
method no longer exist. Useful for coroutine methods, which may outlive
all external references to the object.

The deletion of objects is deferred until the next time slot. This is to
make clearing the triggered flag on named events in classes safe
(otherwise freed memory could be accessed).

Timing support (#3363)
Adds timing support to Verilator. It makes it possible to use delays,
event controls within processes (not just at the start), wait
statements, and forks.

Building a design with those constructs requires a compiler that
supports C++20 coroutines (GCC 10, Clang 5).

The basic idea is to have processes and tasks with delays/event controls
implemented as C++20 coroutines. This allows us to suspend and resume
them at any time.

There are five main runtime classes responsible for managing suspended
coroutines:
* `VlCoroutineHandle`, a wrapper over C++20's `std::coroutine_handle`
  with move semantics and automatic cleanup.
* `VlDelayScheduler`, for coroutines suspended by delays. It resumes
  them at a proper simulation time.
* `VlTriggerScheduler`, for coroutines suspended by event controls. It
  resumes them if its corresponding trigger was set.
* `VlForkSync`, used for syncing `fork..join` and `fork..join_any`
  blocks.
* `VlCoroutine`, the return type of all verilated coroutines. It allows
  for suspending a stack of coroutines (normally, C++ coroutines are
  stackless).

There is a new visitor in `V3Timing.cpp` which:
  * scales delays according to the timescale,
  * simplifies intra-assignment timing controls and net delays into
    regular timing controls and assignments,
  * simplifies wait statements into loops with event controls,
  * marks processes and tasks with timing controls in them as
    suspendable,
  * creates delay, trigger scheduler, and fork sync variables,
  * transforms timing controls and fork joins into C++ awaits

There are new functions in `V3SchedTiming.cpp` (used by `V3Sched.cpp`)
that integrate static scheduling with timing. This involves providing
external domains for variables, so that the necessary combinational
logic gets triggered after coroutine resumption, as well as statements
that need to be injected into the design eval function to perform this
resumption at the correct time.

There is also a function that transforms forked processes into separate
functions.

See the comments in `verilated_timing.h`, `verilated_timing.cpp`,
`V3Timing.cpp`, and `V3SchedTiming.cpp`, as well as the internals
documentation for more details.

Arkadiusz Kozdra 542e324869
Wildcard index type support for associative arrays (#3501).
Associative arrays that specify a wildcard index type may be indexed by
integral expressions of any size, with leading zeros removed
automatically.  A natural representation for such expressions is a
string, especially that the standard explicitly specifies automatic
casts from string indices to bit vectors of equivalent size.
The automatic cast part is done implicitly by the existing type system.

A simpler way to just make this work would be to convert wildcard index
type to a string type directly in the parser code, but several new AST
classes are needed to make sure illegal method calls are detected.
The verilated data structure implementation is reused, because there is
no need for differentiating the behavior on C++ side.

IEEE compliant scheduler (#3384)
This is a major re-design of the way code is scheduled in Verilator,
with the goal of properly supporting the Active and NBA regions of the
SystemVerilog scheduling model, as defined in IEEE 1800-2017 chapter 4.

With this change, all internally generated clocks should simulate
correctly, and there should be no more need for the `clock_enable` and
`clocker` attributes for correctness in the absence of Verilator
generated library models (`--lib-create`).

Details of the new scheduling model and algorithm are provided in
docs/internals.rst.

Geza Lore 9a8c878f2d Avoid repeated traversal for SC text sections in emit when not needed
Repeatedly traversing whole modules in emit (due to file splitting)
looking for `systemc_* sections can add up to a lot of time on large
designs that have been flattened and need to be split into many files.
Assuming `systemc_* is a rarely used feature, just don't bother if we
don't need to. This gain 9% verilation speed improvement on a large
benchmark.
