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.
There are two big categories of changes in here
- Removing lifetimes from common traits that can essentially never user a lifetime from an input (particularly `Drop` & `Debug`)
- Forwarding impls that are only possible because the lifetime doesn't matter (like `impl<R: Read + ?Sized> 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.
- Fixed incorrect `mut` usage
- Fixed style in accordance with tidy
- Marked all methods as unstable
- Changed feature identifier to path_buf_alias_os_string_methods

Implemented the following methods on PathBuf which
forward to the underlying OsString.

- with_capacity

[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()`.
fix Box::into_unique effecitvely transmuting to a raw ptr
Miri/Stacked Borrows treat `Box` specially: they assert that it is unique, and tag it appropriately. However, currently, `Box::into_inner` is not aware of that and returns a raw pointer (wrapped in a `Unique`) that carries the same tag as the box, meaning it carries a `Uniq` tag. This leads to all sorts of problems when people use the raw pointer they get out of the `Unique` type.
In the future, it'd be interesting to make `Unique` also carry some kind of uniqueness. In that case, something like this would instead be needed whenever a raw pointer is extracted from a `Unique`. However, that is out-of-scope for the current version of Stacked Borrows. So until then, this changes `into_unique` to perform a proper reference-to-raw-ptr-cast, which clears the tag.
