First, shuffle cost for scalable type is not known for scalable type; Second, we cannot reason if the narrowed shuffle mask for scalable type is a splat or not. E.g., Bitcast splat vector from type <vscale x 4 x i32> to <vscale x 8 x i16> will involve narrowing shuffle mask <vscale x 4 x i32> zeroinitializer to <vscale x 8 x i32> with element sequence of <0, 1, 0, 1, ...>, which cannot be reasoned if it's a valid splat or not.
