5c30d65683 Auto merge of #93670 - erikdesjardins:noundef, r=nikic
Apply noundef attribute to &T, &mut T, Box<T>, bool

This doesn't handle `char` because it's a bit awkward to distinguish it from `u32` at this point in codegen.

Note that this _does not_ change whether or not it is UB for `&`, `&mut`, or `Box` to point to undef. It only applies to the pointer itself, not the pointed-to memory.

Fixes (partially) #74378.

9d8ef11607 make Instant::{duration_since, elapsed, sub} saturating and remove workarounds
This removes all mutex/atomics based workarounds for non-monotonic clocks and makes the previously panicking methods saturating instead.

Effectively this moves the monotonization from `Instant` construction to the comparisons.

This has some observable effects, especially on platforms without monotonic clocks:

* Incorrectly ordered Instant comparisons no longer panic. This may hide some programming errors until someone actually looks at the resulting `Duration`
* `checked_duration_since` will now return `None` in more cases. Previously it only happened when one compared instants obtained in the wrong order or
  manually created ones. Now it also does on backslides.

The upside is reduced complexity and lower overhead of `Instant::now`.

3cfa4def7c Auto merge of #91403 - cjgillot:inherit-async, r=oli-obk
Inherit lifetimes for async fn instead of duplicating them.

The current desugaring of `async fn foo<'a>(&usize) -> &u8` is equivalent to
```rust
fn foo<'a, '0>(&'0 usize) -> foo<'static, 'static>::Opaque<'a, '0, '_>;
type foo<'_a, '_0>::Opaque<'a, '0, '1> = impl Future<Output = &'1 u8>;
```
following the RPIT model.

Duplicating all the inherited lifetime parameters and setting the inherited version to `'static` makes lowering more complex and causes issues like #61949. This PR removes the duplication of inherited lifetimes to directly use
```rust
fn foo<'a, '0>(&'0 usize) -> foo<'a, '0>::Opaque<'_>;
type foo<'a, '0>::Opaque<'1> = impl Future<Output = &'1 u8>;
```
following the TAIT model.

9c3a3e3d5b Auto merge of #93697 - the8472:fix-windows-path-hash, r=Mark-Simulacrum
Fix hashing for windows paths containing a CurDir component

* the logic only checked for / but not for \
* verbatim paths shouldn't skip items at all since they don't get normalized
* the extra branches get optimized out on unix since is_sep_byte is a trivial comparison and is_verbatim is always-false
* tests lacked windows coverage for these cases

That lead to equal paths not having equal hashes and to unnecessary collisions.

The 8472
1d21ce723c ignore test on wasm32
A fix applied to std::Path::hash triggers a miscompilation/assert in LLVM in this test on wasm32.
The miscompilation appears to pre-existing. Reverting some previous changes done std::Path also trigger it
and slight modifications such as changing the test path from "a" to "ccccccccccc" also make it pass, indicating
it's very flaky.
Since the fix is for a higher-tier platform than wasm it takes precedence.

f45ba82370 Remove SPAN_DEBUG global
The only difference between the default and rustc_interface set version
is that the default accesses the source map from SESSION_GLOBALS while
the rustc_interface version accesses the source map from the global
TyCtxt. SESSION_GLOBALS is always set while running the compiler while
the global TyCtxt is not always set. If the global TyCtxt is set, it's
source map is identical to the one in SESSION_GLOBALS

tidy: Extend error code check

We discovered in https://github.com/rust-lang/rust/pull/93845 that the error code tidy check didn't check everything: if you remove an error code from the listing even if it has an explanation, then it should error.

It also allowed me to put back `E0192` in that listing as well.

linkchecker: fix panic on directory symlinks

In Debian and Ubuntu, there are some patches that change the rustc/fonts
directory to a symlink to the system fonts. This triggers a latent bug
in linkchecker, as the DirEntry filetype isn't a dir but later on the
file itself, when opened, is one, triggering an unreachable!() clause.

This patch fixes the situation by using std::fs::metadata, which goes
through symlinks.

I'd have added a test case but `tidy` doesn't seem to like symlinks, and
moreover I'm not sure how Git deals with symlinks on Windows.

Pretty print ItemKind::Use in rustfmt style

This PR backports the formatting for `use` items from https://github.com/dtolnay/prettyplease into rustc_ast_pretty.

Before:

```rust
use core::{cmp::{Eq, Ord, PartialEq, PartialOrd},
    convert::{AsMut, AsRef, From, Into},
    iter::{DoubleEndedIterator, ExactSizeIterator, Extend, FromIterator,
    IntoIterator, Iterator},
    marker::{Copy as Copy, Send as Send, Sized as Sized, Sync as Sync, Unpin
    as U}, ops::{*, Drop, Fn, FnMut, FnOnce}};
```

After:

```rust
use core::{
    cmp::{Eq, Ord, PartialEq, PartialOrd},
    convert::{AsMut, AsRef, From, Into},
    iter::{
        DoubleEndedIterator, ExactSizeIterator, Extend, FromIterator,
        IntoIterator, Iterator,
    },
    marker::{
        Copy as Copy, Send as Send, Sized as Sized, Sync as Sync, Unpin as U,
    },
    ops::{*, Drop, Fn, FnMut, FnOnce},
};

fix ICE when parsing lifetime as function argument

I don't really like this, but we basically need to emit an error instead of just delaying an bug, because there are too many places in the AST that aren't covered by my previous PRs...
