Add typedExpr data member to Variable like that in Expr. When expression analysis analyzed a Variable it stores the resulting evaluate::Expr there. Add GetExpr overloads in semantics/tools.h for using in statement semantics. It gets an evaluate::Expr from an Expr, Variable, or wrapper around one of those. It returns a const pointer so that clients cannot modify the cached expression (and copies do not have to be made). Change CoarrayChecker to make use of GetExpr. It will eventually replace all references to typedExpr in statement semantics.
