    Move operator_min to the unified range-op table.
    
            * range-op-mixed.h (class operator_min): Move from...
            * range-op.cc (unified_table::unified_table): Add MIN_EXPR.
            (class operator_min): Move from here.
            (integral_table::integral_table): Remove MIN_EXPR.
