Since `LoanPropagation` and `LiveOrigins` are not optional analyses, I think we
can
- remove the optional here.
- construct this unconditionally in
`FactManager::computePersistentOrigins(const CFG&)`
- make `FactManager::getPersistentOrigins()` simply a getter instead of current
getOrCreate semantics.
