func ParseExpression(expr string) (node ast.ExprNode, err error)

ParseExpression parses an ExprNode from a string. Where should we use this?

When TiDB bootstraps, it'll load infoschema from TiKV.
Because some ColumnInfos have attribute `GeneratedExprString`,
we need to parse that string into ast.ExprNode.
