Reading an index store using the APIs provided by `libIndexStore.dylib` is pretty tedious and error-prone due to its manual memory management. Add a Swift wrapper around that API. With the use of non-copyable types and lifetime annotations, this nice Swift interface has no performance overhead compared to accessing the raw C APIs.

libIndexStore.dylibis pretty tedious and error-prone due to its manual memory management. Add a Swift wrapper around that API. With the use of non-copyable types and lifetime annotations, this nice Swift interface has no performance overhead compared to accessing the raw C APIs.I’ve tested the library manually so far but want to add tests before merging this.
Apart from being a nice API for any tool that needs to read an index store and doesn’t want to build on top of indexstore-db, this could the the basis for rewriting indexstore-db in Swift, should we want to one day.
