Rollup merge of #58553 - scottmcm:more-ihle, r=Centril

2019-02-20T03:59:10+00:00

Use more impl header lifetime elision Inspired by seeing explicit lifetimes on these two: - https://doc.rust-lang.org/nightly/std/slice/struct.Iter.html#impl-FusedIterator - https://doc.rust-lang.org/nightly/std/primitive.u32.html#impl-Not And a follow-up to https://github.com/rust-lang/rust/pull/54687, that started using IHLE in libcore. Most of the changes in here fall into two big categories: - Removing lifetimes from common traits that can essentially never user a lifetime from an input (particularly `Drop`, `Debug`, and `Clone`) - Forwarding impls that are only possible because the lifetime doesn't matter (like `impl Read for &mut R`) I omitted things that seemed like they could be more controversial, like the handful of iterators that have a `Item: 'static` despite the iterator having a lifetime or the `PartialEq` implementations [where the flipped one cannot elide the lifetime](https://internals.rust-lang.org/t/impl-type-parameter-aliases/9403/2?u=scottmcm). I also removed two lifetimes that turned out to be completely unused; see https://github.com/rust-lang/rust/issues/41960#issuecomment-464557423
