Allow mismatched widths in operands of shifts in DFG
...
Fixes #3872 .
Testing this is a bit tricky, as the front-end fixes up the operand
widths in shifts to match, and we need V3Const to introduce a mismatched
one by reducing `4'd2 ** x` (with x being 2 2-bit wide signal) to `4'd1
<< x`, but t_dfg_peephole runs with V3Const disabled exactly because it
makes it hard to write tests. Rather than fixing this one case in
V3Const (which we should do systematically at some point), I fixed DFG
to accept these just in case V3Const generates more of them. The
assertions were there only because of paranoia (as I thought these were
not possible inputs), the code otherwise works.

DfgPeephole: Use a work list driven algorithm for speed
...
Replace the 'run to fixed point' algorithm with a work list driven
approach. Instead of marking the graph as changed, we explicitly add
vertices to the work list, to be visited, when a vertex is changed. This
improves both memory locality (as the work list is processed in last in
first out order), and removed unnecessary visitations when only a few
nodes changes.

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.

Optimize clocked processes to comb when referencing const variables
...
In V3Active, we try hard to turn `always @(a or b or c)` into an
`always_comb` if the only variables read in the block are also in the
sensitivity list. In addition, also allow this optimization when reading
variables that are not in the sensitivity list, but are known to be
constant/never changing after initialization. In particular lookup
tables introduced by V3Table are covered by this. This can have a
significant impact on designs that use the `always @(a or b or c)` style
for combinational logic.

Dynamic triggers for non-static contexts ( #3599 )
...
In non-static contexts like class objects or stack frames, the use of
global trigger evaluation is not feasible. The concept of dynamic
triggers allows for trigger evaluation in such cases. These triggers are
simply local variables, and coroutines are themselves responsible for
evaluating them. They await the global dynamic trigger scheduler object,
which is responsible for resuming them during the trigger evaluation
step in the 'act' eval region. Once the trigger is set, they await the
dynamic trigger scheduler once again, and then get resumed during the
resumption step in the 'act' eval region.

Fix null access on optimized-out fork statements ( #3658 )
...
`V3SchedTiming` currently assumes that if a fork still exists, it must
have statements within it (otherwise it would have been deleted by
`V3Timing`). However, in a case like this:
```
module t;
reg a;
initial fork a = 1; join
endmodule
```
the assignment in the fork is optimized out by `V3Dead` after
`V3Timing`. This leads to `V3SchedTiming` accessing fork's `stmtsp`
pointer, which at this point is null. This patch addresses that issue.

DFG: Extract cyclic components separately
...
A lot of optimizations in DFG assume a DAG, but the more things are
representable, the more likely it is that a small cyclic sub-graph is
present in an otherwise very large graph that is mostly acyclic. In
order to avoid loosing optimization opportunities, we explicitly extract
the cyclic sub-graphs (which are the strongly connected components +
anything feeing them, up to variable boundaries) and treat them
separately. This enables optimization of the remaining input.
