        public static ExprReducer.Reduced reduce​(Expr expr)
        Transforms the expression to the format: polynomial + constant, where polynomial is some expression that could not be further simplified and constant is an integer constant value. Generally speaking, the transformation algorithm extracts all expressions that can be statically calculated from the given expression and places their calculated value to the constant field. The remaining part of the expression is placed in the polynomial field.
        Parameters:
        expr - Expression to be reduced.
        Returns:
        A reduced expression.
