// to reuse masks between calls. A vector boolean mask is stored as u16 type
// and converted to bool type right before the call. Transformation is limited
// to the statement group corresponding to `label`.
// If `split_by_and` is true then any ((A & B) & C) mask is split into A, B, C
// sub-masks which are initialized independently. This allows reusing those
// sub-masks for other masks.
