eaf09ba0e7 Dfg: resolve multi-driven signal ranges 
In order to avoid unexpected breakage on multi-driven variables, we
resolve in DFG construction by using only the first driver encountered.
Also issues the MULTIDRIVEN error for these signals.

fb9ec03c3f 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.

6ae6b16223 V3Const: Fix folding of LogAnd with non-bool operands 
Folding an AstLogAnd with a non-zero constant operand used to coerce the
type of the other operand, yielding an ill-typed node that DFG was then
unhappy about. Add a RedOr instead if the width of the replacement
operand is greater than zero.

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
