Geza Lore d60f180f43 Avoid double traversal of maps 
The typical find/if-not-exists-insert pattern can be achieved with 1
lookup instead of 2 using emplace with a sentinel value. Also maps value
initialize their values when inserted with the [] operator, this is
defined and so there is no need to explicitly insert zeroes for integer
values.

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

Geza Lore 63c694f65f Streamline dump control options 
- 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

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.

Implements #3278

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).
