Optimize conditional merging across some impure statements (#7159) 
- Allow reordering pure statements with DPI import calls iff no public
  variables (including those read via a DPI export) are involved. This
  ensures the DPI import can't observe the reordering
- Allow reordering of pure statements with AstDisplay and AstStop. This
  requires an assumption that AstDisplay and AstStop will not read or
  write model state other than via a VarRef explicitly present int the
  Ast.
Overall this allows eliminating a lot of conditionals around assertions,
which were previously not possible.

Add V3LiftExpr pass to lower impure expressions and calls (#7141) 
Introduce new pass that converts impure expressions, or those with
function and method calls into simple assignment statements. Please see
the blurb at the top of the file why this is useful and how it works.
In particular currently it enables more Dfg optimization as functions
will be inlined without AstExprStmt.

Ideally we should enforce this lowering is applied to every procedural
statement (there are still a handful of exceptions). With that, long
term with this pass + #6820, there should be no need to ever use an
AstExprStmt past this new lowering pass, which should enable more easier
optimization down the line.

Also ideally this should be run earlier. Currently it's after V3Tristate
as that calls pinReconnectSimple so we don't have to touch Cell ports.

Currently disabled when code coverage is enabled due to #7119.

Fix inlining of CFuncs with reloop locals (#7132) 
The recent V3InlineCFuncs only checks AstCFunc::varsp for locals, but
V3Reloop used to insert them into AstCFunc::stmtsp resulting in multiple
locals with the same name being inlined into the caller if the stars
align. Fix Reloop. Such things will also go away with #6280.

Internals: Carry 'with' clause as op4 on AstNodeFTaskRef (#7114) 
op4 is now available to carry the 'with' clause explicitly instead of
being part of the argument lit. Will strengthen 'pinsp' to be
List[AstArg] next.
