Internals: Use LogOr/LogAnd on inside operator expansion (#4951)
This will help introducing constrained randomization, as SMT solvers
treat booleans and 1-bit vectors as incompatible types.

Split V3Order.cpp into multiple smaller files (#4950). No functional change intended.
Move OrderBuildVisitor into V3OrderGraphBuilder.cpp (and rename to
V3OrderGraphBuilder). Move ProcessMoveBuildGraph to
V3OrderMoveGraphBuilder.cpp (and rename to V3OrderGraphBuilder).

This patch is pure code movement/rename, no refactoring at all.

Avoid creating redundant vertices in V3DfgPeephole (#4944)
Add a new data-structure V3DfgCache, which can be used to retrieve
existing vertices with some given inputs vertices. Use this in
V3DfgPeephole to eliminate the creation of redundant vertices.

Overall this is performance neutral, but is in prep for some future
work.

Fix DFG removing forceable signals (#4942)
DFG could remove forceable signals by replacing them with their
in-design driver. This is a bit of a pain to prevent, and ideally the
forcing transform should happen before DFG, but implementing it there is
a pain due to having to rewrite ports based on direction.  This is an
attempted fix in DFG. More cases might remain.

Add DFG 'regularize' pass, and improve variable removal (#4937)
This functionality used to be distributed in the removeVars pass and the
final dfgToAst conversion. Instead added a new 'regularize' pass to
convert DFGs into forms that can be trivially converted back to Ast, and
a new 'eliminateVars' pass to remove/repalce redundant variables. This
simplifies dfgToAst significantly and makes the code a bit easier to
follow.

The new 'regularize' pass will ensure that every sub-expression with
multiple uses is assigned to a temporary (unless it's a trivial memory
reference or constant), and will also eliminate or replace redundant
variables. Overall it is a performance neutral change but it does
enable some later improvements which required the graph to be in this
form, and this also happens to be the form required for the dfgToAst
conversion.
