Internals: Make AstWith explicit in AstCMethodHard (#7129) 
This makes it consistent with other usage in NodeFTaskRef. Also AstWith
is no longer a NodeExpr.

Internals: Simplify AstForeach header handling (#7126) 
Rename AstSelLoopVars to AstForeachHeader, and make it a non-NodeExpr.
Tweak parser to always create an AstForeachHeader, so no need to fix it
up later.

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.
