… to copy/clone both Ok and Err
This reverts commit 6c13081.
It's a hot enough path that moving it slightly earlier gives a tiny but easy speedup.
That way, we don't loose the jointness info
Add Result::cloned{,_err} and Result::copied{,_err}
This is a little nice addition to `Result`.
1. I'm not sure how useful are `cloned_err` and `copied_err`, but for the sake of completeness they are here.
2. Naming is similar to `map`/`map_err`. I thought about naming `cloned` as `cloned_ok` and add another method called `cloned` that clones both Ok and Err, but `cloned_ok` should be more prevalent than `cloned_both`.

…mertj libstd fuchsia fixes This fixes two bugs in libstd on Fuchsia: - `zx_time_t` was changed to an `i64`, but this never made it into libstd - When spawning processes where any of the stdio were null, libstd attempts to open `/dev/null`, which doesn't exist on Fuchsia r? @cramertj

…ut_uninit_integers, r=Centril Added warning around code with reference to uninit bytes Officially, uninitialized integers, and therefore, Rust references to them are _invalid_ (note that this may evolve into official defined behavior (_c.f._, rust-lang/unsafe-code-guidelines#71)). However, `::std` uses references to uninitialized integers when working with the `Read::initializer` feature (rust-lang#42788), since it relies on this unstably having defined behavior with the current implementation of the compiler (IIUC). Hence the comment to disincentivize people from using this pattern outside the standard library.
