This commit grepped for LLVM_VERSION_GE, LLVM_VERSION_LT, get_major_version and
min-llvm-version and statically evaluated every expression possible
(and sensible) assuming that the LLVM version is >=9 now
apparently llvm-8-tools already had llvm-8-dev as a dependency
which was removed in llvm-9-tools, so we need to explicitly pull
llvm-9-dev to make a build
Test default values for const parameters.
The last topic on #78433
I originally intended to place these tests in a single file, however, due to them being parser errors that are fatal, they must be in separate files to be detected.
Thanks, ``@lcnr`` for mentoring me on this PR.

Improve the page title switch handling between search and doc
The current behavior often "forgets" to update the page title when discarding/putting back the search results. This isn't optimal which is why I wrote this fix.

extend const generics test suite
should implement most of #78433, especially all parts of [the hackmd](https://hackmd.io/WnFmN4MjRCqAjGmYfYcu2A?view) which I did not explicitly mention in that issue.

Add shortcut for theme picker menu
Follow-up of #78584
Just like you can focus the search input by pressing "S", you can now access the theme picker menu by pressing "T" and navigate through the options only using the keyboard.

Note, in the coverage-reports test, the comment about MacOS was wrong.
The setting is based on config.toml llvm `optimize` setting. There
doesn't appear to be any environment variable I can check, and I
don't think we should add one. Testing the binary itself is a more
reliable way to check anyway.
For the coverage-spanview test, I removed the dependency on sed
altogether, which is much less ugly than trying to work around the
MacOS sed differences.
I tested these changes on Linux, Windows, and Mac.
Update thread and futex APIs to work with Emscripten
This updates the thread and futex APIs in `std` to match the APIs exposed by
Emscripten. This allows threads to run on `wasm32-unknown-emscripten` and the
thread parker to compile without errors related to the missing `futex` module.
To make use of this, Rust code must be compiled with `-C target-feature=atomics`
and Emscripten must link with `-pthread`.
I have confirmed this works well locally when building multithreaded crates.
Attempting to enable `std` thread tests currently fails for seemingly obscure
reasons and Emscripten is currently disabled in CI, so further work is needed to
have proper test coverage here.

Do not collect tokens for doc comments
Doc comment is a single token and AST has all the information to re-create it precisely.
Doc comments are also responsible for majority of calls to `collect_tokens` (with `num_calls == 1` and `num_calls == 0`, cc https://github.com/rust-lang/rust/pull/78736).
(I also moved token collection into `fn parse_attribute` to deduplicate code a bit.)

rustc_target: Move target env "gnu" from `linux_base` to `linux_gnu_base`
Follow up to https://github.com/rust-lang/rust/pull/77729.
Changes the target spec hierarchy for Linux from
```
linux_base
├── linux_musl_base
└── linux_uclibc_base
```
where `linux_base` is really `linux_gnu_base` and the inheriting targets replace target env "gnu" with "musl"/"uclibc" to
```
linux_base
├── linux_gnu_base
├── linux_musl_base
└── linux_uclibc_base
```
which is slightly less confusing (I think).
Support inlining diverging function calls
The existing heuristic does penalize diverging calls to some degree, but since
it never inlined them previously it might need some further modifications.
Additionally introduce storage markers for all temporaries created by
the inliner. The temporary introduced for destination rebrorrow, didn't
use them previously.
Add flags customizing behaviour of MIR inlining
* `-Zinline-mir-threshold` to change the default threshold.
* `-Zinline-mir-hint-threshold` to change the threshold used by
functions with inline hint.
Having those as configurable flags makes it possible to experiment with with
different inlining thresholds and substantially increase test coverage of MIR
inlining when used with increased thresholds (for example, necessary to test
#78844).
