Karan Lokchandani 55d75954e5 Add if let to guard transform (#2420)
fixes: https://github.com/swiftlang/sourcekit-lsp/issues/1569

mostly works but not sure what to do with many edge cases and has a todo
for switch statements, also this will probably have conflicts with
https://github.com/swiftlang/sourcekit-lsp/pull/2406 marking as draft
till that merges and i can resolve the conflicts.
