Monomorphize less code in fs::{read|write}
Since the generic-ness is only for the as_refs, might as well have std just compile the important part once instead of on every use.
Fix search results interactions
The bug is visible when you search for "none": the second tab is empty and therefore it messes with the classes. Then when you try to use arrows on the third tab, it just crashes (because only 2 "search-results" are present and you're on tab 3).

Modify doctest's auto-`fn main()` to allow `Result`s
This lets the default `fn main()` ~~return `impl Termination`~~ unwrap Results, which allows the use of `?` in most tests without adding it manually. This fixes#56260
~~Blocked on `std::process::Termination` stabilization.~~
Using `Termination` would have been cleaner, but this should work OK.
rustdoc: Don't modify library path for doctests
It shouldn't be needed anymore because doctests are no longer compiled with `prefer-dynamic` (since #54939).

ci: fix docker cache hash collision
#58416 uncovered a bug in our caching for docker images: if the image `foo` pulls files from the image `bar` and a file in `bar` changed, the hash of `foo` will be the same even though it should be different. In that PR's case, `dist-i686-linux` pulls scripts from `dist-x86_64-linux`, and the PR only changed those scripts, causing an hash collision for `dist-i686-linux`.
We have to fix this, since the image will be rebuilt every time bors switches from testing master to testing beta/stable (and when it switches back), making CI way more painful than it currently is.
The approach used by this PR is to just include all the files in `src/ci/docker` in the hash. It's a bit heavy-handed and it will cause a rebuild of all the images every time a single image changes, but it's the best I can think of.

Before this commit the hash used to cache docker images was calculated
from the image's files and the files in the scripts/ directory. This
worked fine when all the files used by an image were in those
directories, but some images pull files from other images, causing hash
collisions in some cases.
This commit changes the hash to include the files of all the docker
images, causing a rebuild of all the images when a single one changes.
That's a bit heavy-handed, but we have no way to track which files an
image pulls in and hash collisions are really painful to deal with.
publish_toolstate.py: further fix the runtime errors
The regex was missing a `,`, causing `relevant_pr_match` to become None and set the PR number to -1 and assigned the new issue to `@<unknown user>`. This causes the 422 error when creating the issue due to invalid assignee and unable to leave the tool-is-broken comment since PR -1 does not exist.
The default user names are now also changed to @ghost to prevent the 422 error in case anything goes wrong again.

[CI] Update GCC in the dist-linux builders
Upstream LLVM is planning to raise their minimum toolchain requirements, so they may start using C++14 features. This new policy has already landed in the form of a "soft" error.
http://lists.llvm.org/pipermail/llvm-dev/2019-February/130117.html
For GCC, they will require at least version 5.1. This PR moves our crosstool-ng builders to their max GCC 5.2, with a few small patches to fix compatibility. The dist-x86_64-linux builder is updated to GCC 5.5 and LLVM/Clang 8.0.0-rc2, which also affects dist-i686-linux sharing the same scripts.

Rustdoc remove old style files
Reopening of #56577 (which I can't seem to reopen...).
I made the flag unstable so with this change, what was blocking the PR is now gone I assume.
split MaybeUninit into several features, expand docs a bit
This splits the `maybe_uninit` feature gate into several:
* `maybe_uninit` for what we will hopefully stabilize soon-ish.
* `maybe_uninit_ref` for creating references into `MaybeUninit`, for which the rules are not yet clear.
* `maybe_uninit_slice` for handling slices of `MaybeUninit`, which needs more API design work.
* `maybe_uninit_array` for creating arrays of `MaybeUninit` using a macro (because we don't have https://github.com/rust-lang/rust/issues/49147 yet).
Is that an okay thing to do? The goal is to help people avoid APIs we do not want to stabilize yet. I used this to make sure rustc itself does not use `get_ref` and `get_mut`.
I also extended the docs to advise against uninitialized integers -- again this is something for which the rules are still being discussed.
rustdoc: mask `compiler_builtins` docs
Fixes#46783.
I wasn't able to fully confirm the underlying cause, but my theory is that functions in `compiler_builtins` were overwriting functions with the same names in libcore in the search index. Since the functions in `compiler_builtins` didn't have docs, that's why they weren't appearing in the results.
Masking the `compiler_builtins` crate fixes the search results. It appears that this crate was accidentally unmasked in #49503.
Use posix_spawn_file_actions_addchdir_np when possible
This is a non-POSIX extension implemented in Solaris and in glibc 2.29.
With this we can still use `posix_spawn()` when `Command::current_dir()`
has been set, otherwise we fallback to `fork(); chdir(); exec()`.
