rust/src/libstd/panic.rs, branch 1.34.0

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

Bump to 1.33.0

2018-12-12T16:09:26+00:00

* Update bootstrap compiler * Update version to 1.33.0 * Remove some `#[cfg(stage0)]` annotations Actually updating the version number is blocked on updating Cargo

Various minor/cosmetic improvements to code

2018-12-07T23:53:34+00:00

Do not Atomic{I,U}128 in stage0

2018-11-05T16:54:17+00:00

Correct alignment of atomic types and (re)add Atomic{I,U}128

2018-10-27T10:47:11+00:00

LLVM requires that atomic loads and stores be aligned to at least the size of the type.

it's auto traits that make for automatic implementations

Remove spawning from task::Context
