Update rust-clippy to rustc 1.9.0-nightly (d5a91e695 2016-03-26)

move cfg, infer, traits and ty from middle to top-level
move middle::subst into middle::ty
track the extern-crate def-id rather than path (rustc ab9b844)

 lot of methods that are useful, though one of the most useful would be `expr_ty` (gives the type of
 an AST expression). `match_def_path()` in Clippy's `utils` module can also be useful.
