solaris build environment should include libsendfile/liblgrp
As of version 0.2.120 of the libc crate, the solaris target now requires
some additional libraries to be present in the sysroot. Note that the
solaris target doesn't really build against files from Solaris, but
rather against some files from DilOS (a platform similar to both Solaris
and illumos). Pull in the extra libraries and their compilation links
from that apt repository.
This aims to assist with rust-lang/rust#94052.

Update browser-ui-test version to 0.8.2
It brings mostly debugging improvements: it doesn't stop at the first failing command but rather at the first "fatal error".

Update to Ubuntu 20.04 and crosstool-ng 1.24.0. I've updated the
ct-ng config and then manually reset the kernel and glibc versions
to the oldest supported.
Specifically, we're updating from kernel 2.6.32.68 to 2.6.32.71
and glibc 2.11.1 to 2.12.1 here. The compiler toolchain is also
updated, but I don't think that's relevant for compatibility.

Update dist-x86_64-musl to Ubuntu 20.04
This updates the dist-x86_64-musl image to use Ubuntu 20.04. The current Ubuntu 16.04 based image only works due to the Docker cache, it's not possible anymore to run it locally because of the usual certificate expiration issue.
I believe updating the OS here is relatively safe because this targets musl, so there are no concerns about raising the glibc baseline. There is some risk here in that it updates the compiler toolchain used to produce artifacts, though I'm not aware of any specific issues that could cause.

I believe this should be safe, as actual artifacts will be
produced by a cross toolchain. The build ran through cleanly
locally.

Also update Node to v16.9.0, es-check to 6.1.1, and eslint to 8.6.0.

Update browser-ui-test version and improve rustdoc-gui tests readability
Since the `0.5.1`, we can use trailing commas. I also used the opportunity to clean up the existing tests.

Update certificates in some Ubuntu 16 images.
These images use crosstool-ng, which needs to download various things off the internet. The certificate for `www.kernel.org` no longer works with the ca-certificates in Ubuntu 16. This resolves the issue by grabbing from a newer image a certificate bundle from https://curl.se/ca/cacert.pem, which is usually somewhat up to date.

Build musl dist artifacts with debuginfo enabled
Since our musl targets link to a version of musl we build and bundle
with the targets, if users need to debug into musl or generate
backtraces which contain parts of the musl library, they will be unable
to do so unless we enable and ship the debug info.
This patch changes our dist builds so they enabled debug info when
building musl. This patch also includes a fix for CFI detection in
musl's `configure` script which has been [posted upstream](https://www.openwall.com/lists/musl/2021/10/21/2).
The net effect of this is that we now ship debug info for musl in those
targets. This adds ~90kb to those artifacts but running `strip` on
binaries produced removes all of that. For a "hello world" Rust binary
on x86_64, the numbers are:
| | debug | release | release + strip |
| - | - | - | - |
| without musl debuginfo | 507kb | 495kb | 410kb |
| with musl debuginfo | 595kb | 584kb | 410kb |
Once stripped, the final binaries are the same size (down to the byte).
Fixes #90103

Before, you could have the confusing situation where the command to
generate a component had no relation to the name of that component (e.g.
the `rustc` component was generated with `src/librustc`). This changes
the name to make them match up.

CI: Enable overflow checks for test (non-dist) builds
They stay disabled for Apple builds though, which take the most time already due to running on slow hw.

Update the minimum external LLVM to 12
With this change, we'll have stable support for LLVM 12 and 13.
For reference, the previous increase to LLVM 10 was #83387,
and this replaces the pending increase to LLVM 11 in #90062.

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.

Crosstool-ng 1.22 used by those docker dist builds only allows one
mirror for all downloads.
