Update mdbook
This updates mdbook to 0.4. The list of changes can be found at https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-040. I think the most important one is the change to include fonts with the book instead of using the Google Fonts CDN. This adds a few megabytes of fonts to the docs component. It may be possible to share the fonts across the books, but would take a fair bit of work to make that happen, so I'm not sure if it is necessary.
This also removes mdbook-linkcheck. It is currently not being used, and I don't foresee it going back into use anytime soon. I would prefer not to maintain something that isn't being used, and it removes a very large number of dependencies.

ci: allow gating GHA on everything but macOS
In our GitHub Actions setup macOS is too unreliable to gate on it, but the other builders work fine. This commit splits the macOS builders into a separate job (called `auto-fallible`), allowing us to gate on the auto job without failing due to macOS spurious failures.

ci: disable alt build during try builds
The alt build is not actually needed often, and it can be added back on a case-by-case basis if a specific PR needs access to it.
This will free up a builder.

When we're running with dry_run enabled (i.e. all builds do this initially), we're
guaranteed to save of a toolstate of TestFail for tools that aren't tested. In practice,
we do test tools as well, so for those tools we would initially record them as being
TestPass, and then later on re-record the correct state after actually testing them.
However, this would not work well if the build failed for whatever reason (e.g. panicking
in bootstrap, or as was the case in 73097, clippy failing to test successfully), we would
just go on believing that things passed when they in practice did not.
This commit also adjusts saving toolstate to never record clippy explicitly (otherwise, it
would be recorded when building it); eventually that'll likely move to other tools as well
but not yet. This is deemed simpler than checking everywhere we generically save
toolstate.
We also move clippy out of the "toolstate" no-fail-fast build into a separate x.py
invocation; this should no longer be technically required but provides the nice state of
letting us check toolstate for all tools and only then check clippy (giving full results
on every build).

Remove vestigial CI job msvc-aux.
This CI job isn't really doing anything, so it seems prudent to remove it.
For some history:
* This was introduced in #48809 when the msvc job was split in two to keep it under 2 hours (oh the good old days). At the time, this check-aux job did a bunch of things:
* tidy
* src/test/pretty
* src/test/run-pass/pretty
* src/test/run-fail/pretty
* src/test/run-pass-valgrind/pretty
* src/test/run-pass-fulldeps/pretty
* src/test/run-fail-fulldeps/pretty
* Tidy was removed in #60777.
* run-pass and run-pass-fulldeps moved to UI in #63029
* src/test/pretty removed in #58140
* src/test/run-fail moved to UI in #71185
* run-fail-fulldeps removed in #51285
Over time through attrition, the job was left with one lonely thing: `src/test/run-pass-valgrind/pretty`. And of course, this wasn't actually running the "pretty" tests. The normal `run-pass-valgrind` tests ran, and then when it tried to run in "pretty" mode, all the tests were ignored because compiletest thought nothing had changed (apparently compiletest isn't fingerprinting the mode? Needs more investigation…). `run-pass-valgrind` is already being run as part of `x86_64-msvc-1`, so there's no need to run it here.
I've taken the liberty of removing `src/test/run-pass-valgrind/pretty` as a distinct test. I'm guessing from the other PR's that the pretty tests should now live in `src/test/pretty`, and that the team has moved away from doing pretty tests on other parts of the `src/test` tree.

[CI] Use the latest Python available on Windows
This PR changes our Windows CI to always use the latest Python interpreter available in the GHA tool cache instead of hardcoding Python 3.7.6. This is needed because occasionally GitHub bumps the installed version, deleting the previous one.
This fixes the current GHA outage we're having. I fully expect the outage to propagate to Azure Pipelines in the coming days if we don't merge this, as both GHA and Azure use the same underlying image. Once the PR is merged we can re-enabled the double-gating.

Ensure that `./x.py doc --stage 0 src/libstd` works via CI
This was split off from #71645, which recommends that users first try building `libstd` docs with the bootstrap `rustdoc`. This should work in most cases, but will fail if we start using a very recent `rustdoc` feature outside a `#[cfg(not(bootstrap))]`.
It would be very nice to guarantee that `./x.py doc --stage 0 src/libstd` works, since it allows documentation changes to be rendered locally without needing to build the compiler. However, it may put too big a burden on `rustdoc` developers who presumably want to dogfood new features.

We don't clone the repository in those builders, so the default shell
(src/ci/exec-with-shell.py) is not present there.

Enable "full tools" option on ARM dist builders
This commit switches the `--enable-extended` option on the arm-related
dist builders to `--enable-full-tools`. This alias in `config.py`
corresponds to enabling a few more options:
* `rust.lld = true` - this is the main purpose of this PR, to enable LLD
on ARM-related platforms. This means it will effectively unlock
compilation of wasm programs from an arm host.
* `rust.llvm-tools = true` - it turns out that this option is largely
ignored in rustbuild today. This is only read in one location to set
some flags for the `llvm-tools` package, but the `llvm-tools` package
is already produced on all of these builders. It's predicted that this
will have no effect on build times.
* `rust.codegen-backends = ['llvm']` - historically this also enabled
the emscripten backend, but that has long since been removed.
This brings the ARM dist builders in line with the x86_64 dist builders
using this flag. The hope is that the extra time spent on CI building
LLD will acceptable because it's cached by `sccache`, LLD is a
relatively small C++ project, and the dist builders are all clocking
well under 3 hours (the slowest of all builders) around 2 hours.
There's likely some possible cleanup that can happen with these
configure options since it doesn't look like they've aged too too well,
but I'm hopeful that possible refactorings, if necessary, could be
deferred to future PRs.

ci: run mir-opt tests on PR CI also as 32-bit (for `EMIT_MIR_FOR_EACH_BIT_WIDTH`).
Background: #69916 and [`src/test/mir-opt/README.md`](https://github.com/rust-lang/rust/blob/master/src/test/mir-opt/README.md):
> By default 32 bit and 64 bit targets use the same dump files, which can be problematic in the
presence of pointers in constants or other bit width dependent things. In that case you can add
>
> ```
> // EMIT_MIR_FOR_EACH_BIT_WIDTH
> ```
>
> to your test, causing separate files to be generated for 32bit and 64bit systems.
However, if you change the output of such a test (intentionally or not), or if you add a test and it varies between 32-bit and 64-bit platforms, you have to run this command (for a x64 linux host):
`./x.py test --stage 1 --target x86_64-unknown-linux-gnu --target i686-unknown-linux-gnu --bless src/test/mir-opt`
Otherwise, bors trying to merge the PR will fail, since we test 32-bit targets there.
But we don't on PR CI, which means there's no way the PR author would know (unless they were burnt by this already and know what to look for).
This PR resolves that by running `mir-opt` tests for ~~`i686-unknown-linux-gnu`~~, on PR CI.
**EDIT**: switched to `armv5te-unknown-linux-gnueabi` to work around LLVM 7 crashes (see https://github.com/rust-lang/compiler-builtins/pull/311#issuecomment-612270089), found during testing.

Stop explicitly depending on python 2
This PR revises our previous policy of officially only supporting and testing with python 2 in the CI environment to instead test with python 3. It also changes the defaults to python 3 in our various scripts (usually, by way of `python` rather than `python3` to preserve compatibility with systems that do not have a python 3 available).
The effect of this is that we expect all new patches to support python 3 (and will test as such). We explicitly also expect that patches support python 2.7 as well -- and test as such, though only on one builder. This is intended as a temporary, though likely long-lived, measure to preserve compatibility while looking towards the future which is likely to be a python 3 only world. We do not at this point set a timeline for when we'll drop support for python 2.7; it's plausible that this is months or years into the future, depending on how quickly the ecosystem drops support and how painful it is for us to maintain that support over time.
Closes #65063 (as far as I can tell; please file explicit and separate issues or PRs if not).

Enable rust-lld on dist-x86_64-musl
Add rust-lld to rustup llvm-tools-preview on nightly for musl
I am using a musl distro on my workstation, with `RUSTFLAGS="-C target-feature=-crt-static"` this works fine. I know that `x86_64-unknown-linux-musl` was originally only meant as a target and not as a host. But most problems have been fixed, and I have fewer problems with `unknown` (rustup) than when I am using `x86_64-alpine-linux-musl` (rust installed by the distro). The only thing I am missing is rust-lld in llvm-tools-preview on nightly.
I needed rust-lld for a wasm tutorial. I built rust-lld and tested it with that tutorial, and it worked well. I asked [here](https://users.rust-lang.org/t/enable-rust-lld-on-x86-64-unknown-linux-musl/39851) where to request to enable lld and ended up doing this PR.
I compared llvm-tools-preview `nightly-x86_64-unknown-linux-musl` and `nightly-x86_64-unknown-linux-gnu`: only rust-lld is missing in musl.
I tested the change using:
```bash
./src/ci/docker/run.sh dist-x86_64-musl
```
And I checked that the resulting rust-lld binary runs.
