CI: make docker cache download and `docker load` time out after 10 minutes
Might help to prevent timeouts we have been seeing:
* https://github.com/rust-lang-ci/rust/runs/3946294286?check_suite_focus=true#step:25:23
* https://github.com/rust-lang-ci/rust/runs/3956799200?check_suite_focus=true#step:25:22
* https://github.com/rust-lang-ci/rust/runs/3962928502?check_suite_focus=true#step:25:23
* https://github.com/rust-lang-ci/rust/runs/3967892291?check_suite_focus=true
* https://github.com/rust-lang-ci/rust/runs/3971202204?check_suite_focus=true
If the download or loading the images into docker times out the CI will still continue and rebuild the docker image from scratch.

Add test for line-number setting
The first commit updates the version of the package to be able to have multi-line commands (which looks much nicer for this test).

Split out LLVM PGO step and use clang 13 to compile LLVM
We're seeing a PGO version mismatch error in CI logs:
LLVM Profile Error: Runtime and instrumentation version mismatch : expected 5, but get 7
which is likely due to the version bumped here differing from that used by
rustc.
This PR fixes this by splitting out the PGO step for LLVM into a separate phase of the pgo.sh script, which nets no change to performance (see [these results](https://perf.rust-lang.org/compare.html?start=c34ac8747ca96d09cb08b8f5adddead826e77c06&end=e272c2af45f40c74dab83948235903ffbe3ad57f)). Then, it follows that up with an upgrade to LLVM/clang version 13 as our bootstrap compiler, which yields the performance improvements for this PR -- around 5%. This depends on the first step here, because otherwise we end up somehow clobbering or otherwise hurting our ability to effectively collect performance data, yielding reductions in performance for a subset of benchmarks -- it is not clear what the cause here was precisely, but the split only costs ~10 minutes and seems worthwhile.

This commit updates the wasi-libc that we include with the wasm32-wasi
target, which brings in various misc fixes such as musl updates and some
math tweaks.

This skips bumping Windows sccache because we run into compilation failures when
doing so (-m32 not supported by clang-cl?). Not clear on cause, but seems
easiest to just hold back.
This should avoid PGO-related failures encountered on Linux, and more broadly
seems like a good idea on other platforms as well (though it is likely not
necessary right this moment).

This shows up to 5% less instruction counts on multiple benchmarks, and up to
19% wins on the -j1 wall times for rustc self-compilation.
We can afford to spend the extra cycles building LLVM essentially once more for
the x86_64-unknown-linux-gnu CI build today. The builder finishes in around 50
minutes on average, and this adds just 10 more minutes. Given the sizeable
improvements in compiler performance, this is definitely worth it.

Remove git fetch from CI
https://github.com/rust-lang/rust/pull/86623 added a call to `git fetch`, which is problematic for releases.

This is needed to handle R_X86_64_REX_GOTPCRELX relocations.

The LLD + ThinLTO __morestack bug has been fixed in 12.0.1, so
we can now update our clang version. This also means that we no
longer need to build Python 2.

Use HTTPS links where possible
While looking at #86583, I wondered how many other (insecure) HTTP links were in `rustc`. This changes most other `http` links to `https`. While most of the links are in comments or documentation, there are a few other HTTP links that are used by CI that are changed to HTTPS.
Notes:
- I didn't change any to or in licences
- Some links don't support HTTPS :(
- Some `http` links were dead, in those cases I upgraded them to their new places (all of which used HTTPS)

This is needed as they are built on a long-outdated Debian version. :(

During the 1.52 release process we had to deal with some commits that
passed the test suite on the nightly branch but failed on the beta or
stable branch. In that case it was due to some UI tests including the
channel name in the output, but other changes might also be dependent on
the channel.
This commit adds a new CI job that runs the Linux x86_64 test suite with
the stable branch, ensuring nightly changes also work as stable.

Build crtbegin.o/crtend.o from source code
Build crtbengin.o/crtend.o from source code instead of copying from gcc.
The crtbegin and crtend implementation from llvm don't need `crtbeginS.o` for PIC. `crtbegin{,S,T}.o` is unified into one generic `crtbegin.o`. See the comments in https://reviews.llvm.org/D28791#1419436 and https://reviews.llvm.org/D28791#1420914

Add eslint checks to CI
It also allowed me to fix some potential issues that went unnoticed. Having this process automated will hopefully prevent us to add more errors. :)
