/*
 * Summary: This macro is used to get Variable or internal type
 *   data (such as LoDTensor or SelectedRows) of the Input and
 *   Output in op, generally used when call scope.FindVar(Input/
 *   Output("Name")) or ctx.Input<LoDTensor>().
 *   Firstly this macro check whether the obtained pointer is null,
 *   and then return data if it is not null.
 *
 * Note: This macro is only suitable for specific scenarios and
 *   does not intended to be widely used. If it cannot meet the
 *   requirements, please use other PADDLE_ENFORCE** check macro.
 *
 * Parameters:
 *     __PTR: pointer
 *     __ROLE: (string), Input or Output
 *     __NAME: (string), Input or Output name
 *     __OP_TYPE: (string), the op type
 *  
 * Return: The data pointed to by the pointer.
 *
 * Examples:
 *    GET_DATA_SAFELY(ctx.Input<LoDTensor>("X"), "Input", "X", "Mul");
