Before CL 62530 fastrand always returned non-zero value, and one condition in sema.go depends on this behavior. fastrand is used to generate random weight for treap of sudog, and it is checked against zero to verify sudog were inserted into treap or wait queue. Since its precision is not very important for correctness, lets just always set its lowest bit in this place.
