- Fixed a bug in the linalg shape inference - where a shape is reused by accident. Instead, input shapes are cloned before inference occurs. - Boyscout cleanups

Originally due to the behaviour of the `sliceOp` at runtime, the resulting tensor is not materialized. This made things very difficult for optimization - it's cheaper to materialize each step of a slice. As a result, the raw .Data() no longer contains the extra data. A concrete example: ``` a := NewMatrix(g, float64, WithShape(3, 2), WithName("a"), WithInit(RangedFrom(0))) x := Slice(a, nil, S(0)) m := NewTapeMachine(g) m.RunAll() x.Value() // will be a colvec: // [0] // [2] // [4] ``` In the old version, the slice operation doesn't materialize, so `x.Value()` is the same, but the raw data, acquired by `.Data()` is `[0, 1, 2, 3, 4]` Now it has been materialized, so the raw data from `x.Value().Data()` will simply be `[0 2 4]`
