on 32bit -- Series is int64 but cut produces int32 series #14866

Code Sample, a copy-pastable example if possible
failing on 32bit test

so I guess if Series should use int64 regardless of underlying architecture default type, then cut should also produce int64, I guess.... or should Series have arch-default int??
