Geza Lore f5a226a183 Partial clean up of V3Order. No functional change intended.
This is a partial cleanup of V3Order with the aim of increasing clarity:
- Split the initial OrderGraph building and the actual ordering process
into separate classes (OrderVisitor -> OrderBuildVisitor + OrderProcess)
- Remove all the historical cruft from the graph building phase (now in
OrderBuildVisitor), and add more assertions for assumptions.
- Change the dot styling of OrderGraph to use shapes and more easily
distinguishable colors.
- Expand vague comments, remove incorrect comments, and add more.
- Replace some old code with cleaner C++11 constructs.
- Move code about a bit so logically connected sections are closer to
each other, scope some definitions where they are used rather than file
scope.
- The actual ordering process (now in OrderProcess) is still largely
unchanged.

The generated code is identical to before (within the limits of the
exiting non-determinism).

Geza Lore 5515eed0b6 Make AstTopScope accessible from AstNetlist
AstTopScope is a singleton node and making it accessible without a
traversal simplifies some code and decouple some other.

Geza Lore 70603bb752 Add static assertions for unnecessary VN_IS/VN_AS/VN_CAST
Fail at compile time if the result of these macros can be statically
determined (i.e.: they aways succeed or always fail). Remove unnecessary
casts discovered. No functional change.

Fix re-evaluation of logic dependent on state set in DPI exports (#3091).
Verilator should now correctly re-evaluate any logic that depends on
state set in a DPI exported function, including if the DPI export is
called outside eval, or if the DPI export is called from a DPI import.

Whenever the design contains a DPI exported function that sets a
non-local variable, we create a global __Vdpi_export_trigger flag, that
is set in the body of the DPI export, and make all variables set in any
DPI exported functions dependent on this flag (this ensures correct
ordering and change detection on state set in DPI exports when needed).
The DPI export trigger flag is cleared at the end of eval, which ensured
calls to DPI exports outside of eval are detected. Additionally the
ordering is modifies to assume that any call to a 'context' DPI import
might call DPI exports by adding an edge to the ordering graph from the
logic vertex containing the call to the DPI import to the DPI export
trigger variable vertex (note the standard does not allow calls to DPI
exports from DPI imports that were not imported with 'context', so we
do not enforce ordering on those).

Emit model implementation as loose methods. (#3006)
This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.

Split procedures to better respect --output-split-cfuncs (#2942)
CFuncs only used to be split at procedure (always/initial/final block),
which on occasion can still yield huge output files if they have large
procedures. This patch make CFuncs split at statement boundaries within
procedures. This has the potential to help a lot, but still does not
help if there are huge statements within procedures.
