This replaces the lasso-shaped encodings in the word-level BMC property encoding. The lasso and straigth-line encodings are now built as separate obligations. In the lasso encoding, all operators follow the same lasso shape. This avoids spurious traces where the eventually operator follows the lasso but a safety part of the property does not.
