Overal looks fine.
Try spliting bigger parts of code int some lambdas or functions, so it could be more readable, consider adding some 1 line comments specially when fixes are created to point out what those insertions/replacement/deletions are.
Check code for missing checks (nullptr, iterators).

In general consider replacing some std::vector with llvm::SmallVector with some preallocated memofry, like for 2 or 32 elements, depend on needs
