[NFC] Use ParentIndexIterator in SmallVector#7826
Merged
Conversation
SmallVector previously (partially) implemented its own random access iterators using a pointer to the parent SmallVector and an index, but ParentIndexIterator is a more complete implementation of the same iterator design. Reduce duplication and fix missing iterator functionality by using ParentIndexIterator.
