CI: update `rustc-perf` version used in CI and also the corresponding PGO benchmarks
The old version was from May 2021. The `rustc-perf` benchmarks have seen a significant overhaul recently, so let's see if the new benchmarks can improve PGO performance.
Promote x86_64-unknown-none target to Tier 2 and distribute build artifacts
This implements https://github.com/rust-lang/compiler-team/issues/499 , in which the compiler team accepted the x86_64-unknown-none target for promotion to a Tier 2 platform.
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".

Gather LLVM PGO profiles from `rustc-perf` suite on real-world crates
This PR expands the benchmark suite used to gather LLVM PGO profiles in CI from `libcore` to several real-world crates. I hand-picked a few crates, but the list is up for debate.
Previous results that we got from running `syn,cargo,serde` looked pretty [good](https://perf.rust-lang.org/compare.html?start=2631aeef823a9e16d31f999d3f07001e5fcc4b3d&end=abf097afa10dde1aa3d8a1d422724a46aab79bf3).
Running `libcore` + `rustc-perf` with some number of crates is repeated now (and for BOLT it will also be needed), so maybe we can extract it to a bash function?
r? `@Mark-Simulacrum`
For some reason, `tar` behaves differently in such a way that it does
not create symlinks on Windows correctly, resulting in
`Cannot create symlink to 'ld.gold': No such file or directory`
errors.
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.

Update dist-(arm|armv7|armhf)-linux to Ubuntu 20.04
I believe this should be safe, as actual artifacts will be produced by a cross toolchain. The build ran through cleanly locally.
This came up in https://github.com/rust-lang/rust/pull/93577, where the host GCC ICEd during the LLD build. (Though I wonder why we build LLD for the host at all...)

Update CPU idle tracking for apple hosts
The previous setup did not properly consider hyperthreads (at least in local
testing), which likely skews CI results as well. The new code is both simpler
and hopefully will produce more accurate results; locally it matches behavior
of the Linux version of this script.

This builder is the slowest in the fleet. This should cut a considerable
amount of time. The manifest should now include the docs from
x86_64-apple-darwin. Although those docs are slightly different, it
should be close enough. When aarch64-apple-darwin heads towards tier 1,
we can revisit whether or not to re-enable the docs.
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.
