rustdoc: move collapse and unindent docs passes earlier
Moves these passes as early as possible so later passes will see the same markdown that is passed to the test collector.
Fixes#58473, and a similar issue with the private-doc-tests lint.

Fix for issue #58050
Hi,
a quick PR to mention in the compiler error message that `?` is a macro operator, as according to issue #58050
It passed `python x.py test src/tools/tidy` locally, as well as the recommendation to run `/x.py test src/test/ui --stage 1 --bless`.
Let me know if anything else is needed.
Allow lang and lib features to share names
Fixes https://github.com/rust-lang/rust/issues/58715.
I didn't add a test, because there's currently no standard lang test feature and I felt apprehensive about adding a permanently unstable feature. Instead, a shared lang/lib feature will be used in https://github.com/rust-lang/rust/pull/57760 and will essentially provide an immediately test.
Update stdsimd
This updates stdsimd to a Rust2015 / Rust2018 compatible version. Once this is merged it should be possible to migrate libcore and libstd to Rust2018. Once that happens, we can just require the 2018 edition in stdsimd.
This commit updates the LLVM branch to the rebased version of the
upstream release/8.x branch. This includes a wasm patch which means that
the `rewrite_imports` pass in rustc is no longer needed (yay!) and we
can instead rely on `wasm-import-module`, an attribute we're already
emitting, to take care of all the work.
* A number of `Stdio` related doc examples include running the "rev"
command to illustrate piping commands. The majority of these tests are
marked as `no_run` except for two tests which were not
* Not running these tests is unlikely to cause any negative impact, and
doing so also allows the test suite to pass in environments where the
"rev" command is unavailable
Add vectored read and write support
This functionality has lived for a while in the tokio ecosystem, where
it can improve performance by minimizing copies.

Stabilize `unrestricted_attribute_tokens`
In accordance with a plan described in https://internals.rust-lang.org/t/unrestricted-attribute-tokens-feature-status/8561/3.
Delimited non-macro non-builtin attributes now support the same syntax as macro attributes:
```
PATH
PATH `(` TOKEN_STREAM `)`
PATH `[` TOKEN_STREAM `]`
PATH `{` TOKEN_STREAM `}`
```
Such attributes mostly serve as inert proc macro helpers or tool attributes.
To some extent these attributes are de-facto stable due to a hole in feature gate checking (feature gating is done too late - after macro expansion.)
So if macro *removes* such helper attributes during expansion (and it must remove them, unless it's a derive macro), then the code will work on stable.
Key-value non-macro non-builtin attributes are now restricted to bare minimum required to support what we support on stable - unsuffixed literals (https://github.com/rust-lang/rust/issues/34981).
```
PATH `=` LITERAL
```
(Key-value macro attributes are not supported at all right now.)
Crater run in https://github.com/rust-lang/rust/pull/57321 found no regressions for this change.
There are multiple possible ways to extend key-value attributes (https://github.com/rust-lang/rust/pull/57321#issuecomment-451574065), but I'd expect an RFC for that and it's not a pressing enough issue to block stabilization of delimited attributes.
Built-in attributes are still restricted to the "classic" meta-item syntax, nothing changes here.
https://github.com/rust-lang/rust/pull/57321 goes further and adds some additional restrictions (more consistent input checking) to built-in attributes.
Closes https://github.com/rust-lang/rust/issues/55208

Deny the `overflowing_literals` lint for all editions
The `overflowing_literals` was made deny by default for the 2018 edition by #54507, however I'm not aware of any reason it can't be made deny by default for the 2015 edition as well.
