Run `tests/ui/backtrace/std-backtrace.rs` on MSVC.
The original PR which disabled these, https://github.com/rust-lang/rust/pull/62897, only mentions them being broken on i686. ~~let's still make sure the rest of windows is supported.~~ Let's see if we can enable this for msvc now (32-bit and 64-bit).

Update `#[coverage(..)]` attribute error messages to match the current implementation
The allowed positions for `#[coverage(..)]` attributes were expanded by #126721, but the corresponding error messages were never updated to reflect the new behaviour.
Part of #134749.
Default to short backtraces for dev builds of rustc itself
A dev build almost certainly means that whoever's built the compiler has the opportunity to rerun it to collect a more complete trace. So we don't need to default to a complete trace; we should hide irrelevant details by default.
compiletest: Support `forbid-output` in UI tests
The `forbid-output` directive is currently only run in incremental tests (although no incremental tests use it). There are some UI tests 'using' it, but it's doing nothing 😄 Let's fix this
Will also PR the dev guide to note this.

Consider arm to diverge if guard diverges
This is not a fix for #134734, but I discovered it when I was gauging how difficult it would be to fix that. It does fix a really old test though :>

- fix(package): check dirtiness of path fields in manifest (rust-lang/cargo#14966)
- test: make path arguments more generic and flexible (rust-lang/cargo#14979)
- Moved manifest metadata tracking from fingerprint to dep info (rust-lang/cargo#14973)
- fix: assure possibly blocking non-files (like FIFOs) won't be picked up for publishing. (rust-lang/cargo#14977)
- simplify SourceID Hash (rust-lang/cargo#14800)
- upgrade `gix` to the latest release 0.69. (rust-lang/cargo#14975)

Windows: Use FILE_ALLOCATION_INFO for truncation
We use `FILE_END_OF_FILE_INFO` here only because WINE does not support `FILE_ALLOCATION_INFO`. Instead of going with the one with broadest support, let's just use that as fallback only.
Correctly note item kind in `NonConstFunctionCall` error message
Don't just call everything a "`fn`". This is more consistent with the error message we give for conditionally-const items, which do note the item's def kind.
r? fmease, this is a prerequisite for making those `~const PartialEq` error messages better. Re-roll if you're busy or don't want to review this.
core: fix const ptr::swap_nonoverlapping when there are pointers at odd offsets
Ensure that the pointer gets swapped correctly even if it is not stored at an aligned offset. This rules out implementations that copy things in a `usize` loop -- so our implementation needs to be adjusted to avoid such a loop when running in const context.

Fix safety docs for `dyn Any + Send {+ Sync}`
Fixes the `# Safety` docs for `dyn Any + Send`'s `downcast_{mut/ref}_unchecked` to show the direct instructions , where previously the would tell the user to find the docs on `dyn Any` themselves.
This also adds them for `downcast_{mut/ref}_unchecked` on `dyn Any + Send + Sync`
Begin to implement type system layer of unsafe binders
Mostly TODOs, but there's a lot of match arms that are basically just noops so I wanted to split these out before I put up the MIR lowering/projection part of this logic.

Always run `tail_expr_drop_order` lint in promoted MIR query
Rather than running the lint at the beginning of `mir_drops_elaborated_and_const_checked`, run it at the end of `mir_promoted`. This should ensure that the lint gets picked up when running `cargo fix`, which runs with `--emit metadata` and therefore doesn't actually query `mir_drops_elaborated_and_const_checked`.
We could probably push this down into `mir_built` too? but I don't really see a good reason to do so.

Generate shell completions for x as well
It would be nice to be have shell completions for both `./x` and `x` (installed with `cargo install --path src/tools/x`) instead of just `x.py`. This pr generates the corresponding completions for each shell in a similar way to `x.py` but under `x.<shell>` instead.
