Thanks for the patch. IIUC this patch does 2~3 things:

- Add a `dump()` method to `Attr`
- Refactor the pertaining transformation logic of `TransformLambdaExpr()`
- Refactor some other logic in `ASTContext::AdjustType()`

They're really great works, but I suggest we split up the patch to make the code review easier, WDYT?
