Refactor unwind in MIR
This makes unwinding from current `Option<BasicBlock>` into
```rust
enum UnwindAction {
Continue,
Cleanup(BasicBlock),
Unreachable,
Terminate,
}
```

Fix buffer overrun in bootstrap and (test-only) symlink_junction
I don't think these can be hit in practice, due to their inputs being valid paths. It's also not security-sensitive code, but just... bad vibes.
I think this is still not really the right way to do this (in terms of path correctness), but is no worse than it was.

extend `detect_src_and_out` test
> I was thinking about the following cases when I wrote the comment in #109055

Tested all the topics mentioned above. All worked fine. The test is now also covers if build dir is manually specified in config.

Update to LLVM 16.0.1
Update to current `release/16.x` branch. I've opted for a rebase to get rid of all our custom cherry-picks.
Fixes#109775.

write threads info into log only when debugging
The current tracing log will unconditionally write thread information during parallel compilation, which sometimes confuses some normal output log information
This fixes the UI test failure of:
```
[ui] tests/ui/consts/const_in_pattern/issue-73431.rs
```
Updates #75760
Validate `ignore` and `only` compiletest directive, and add human-readable ignore reasons
This PR adds strict validation for the `ignore` and `only` compiletest directives, failing if an unknown value is provided to them. Doing so uncovered 79 tests in `tests/ui` that had invalid directives, so this PR also fixes them.
Finally, this PR adds human-readable ignore reasons when tests are ignored due to `ignore` or `only` directives, like *"only executed when the architecture is aarch64"* or *"ignored when the operative system is windows"*. This was the original reason why I started working on this PR and #108659, as we need both of them for Ferrocene.
The PR is a draft because the code is extremely inefficient: it calls `rustc --print=cfg --target $target` for every rustc target (to gather the list of allowed ignore values), which on my system takes between 4s and 5s, and performs a lot of allocations of constant values. I'll fix both of them in the coming days.

submodule detection for proper fix on #96188
This commit resolves an internal FIXME note within the bootstrap by implementing submodule detection. This is accomplished through an iterative process over the `.gitmodules` file.

Remove the use of `-use-gnu-stack` when BOLTing LLVM
This flag was (counterintuitively) removing the `GNU_STACK` ELF attribute, which caused the optimized `libLLVM.so` file to be flagged as having an executable stack on SELinux.
Removing the flag might cause issues with `strip`. I'm not aware that we're stripping `libLLVM.so` though. Does it happen anywhere?

Don't collect return-position impl traits for documentation
#104889 modified the rustdoc ast collection step to use a HIR visitor, which more thoroughly walks the HIR tree. that means that we're going to encounter inner items (incl return-position impl traits and async fn opaque futures) that are not possible to document.
FIxes (but does not close due to being a beta regression) #109931

rustdoc: escape GAT args in more cases
Fixes#109488.
Previously we printed the *un*escaped form of GAT arguments not only when `f.alternate()` was true but *also* when we failed to compute the URL of the trait associated with the type projection, i.e. when `href(…)` returned an `Err(_)`.
In this PR the argument printing logic is entirely separate from the link resolution code above as it should be.
Further, we now only try to compute the URL if the HTML format was requested with `!f.alternate()`. Before, we would sometimes compute the `href` only to throw it away later.
Remove optimal xz settings from CI
This is a companion PR to rust-lang/promote-release#58, which moves the relevant optimal code to rust-lang/promote-release. As mentioned in the comments of that PR, this is expected to cut CI costs (and time, though predominantly felt on fast builders) and reduce wasted resources due to in-practice single-threaded compression not using the full 8+ vCPU builders we have available.
This probably shouldn't land before that PR + a simpleinfra change to enable the recompression of xz artifacts. But if it does land, it's just a matter of a few nightlies with slightly larger artifacts, so not a big deal.

rustdoc: make intra-doc link pass non-quadratic for repeated links
In the collect_intra_doc_links pass, links to a given item that occurred repeatedly were getting inserted into a `Vec<clean::ItemLink>` repeatedly. This led to n^2 behavior (where n = the number of pages generated), particularly for the intra-doc link on the `Into<U> for T where U: From<T>` blanket implementation, since that link appears on every single struct page.
Fixes#109851
