Rollup merge of #111602 - tmiasko:erroneous-constant-used, r=oli-obk
Suppress "erroneous constant used" for constants tainted by errors

When constant evaluation fails because its MIR is tainted by errors,
suppress note indicating that erroneous constant was used, since those
errors have to be fixed regardless of the constant being used or not.

Fixes #110891.

Rollup merge of #111572 - kpreid:mdi, r=compiler-errors
Document that `missing_copy_implementations` and `missing_debug_implementations` only apply to public items.

I encountered #111359 (fixed) and noticed that the documentation didn't say that it was _intended_ that `missing_debug_implementations` only applies to public items. This PR fixes that, and makes the same wording change to `missing_copy_implementations` which has the same condition.

I chose the words to also be similar to `missing_docs` which already had such a remark.

Alternatively, happy to close this if we're okay with just saying "sorry #111327 is just a poor side-effect of parser ambiguity" 🤷

Remove unnecessary Send bound

Hi,

While working on a [PR on Tokio](https://github.com/tokio-rs/tokio/pull/5666), I took inspiration from the std channel mpsc and stumbled on a `Send` bound for a `Error` impl.

Tokio's maintainer `@Darksonn` pointed out to me that `Error` used to required the `Send` bound long time ago (here https://github.com/rust-lang/rust/pull/23541).

In the meantime, the `Send` bound `Error` got removed (see https://github.com/rust-lang/rust/pull/21312 and https://github.com/rust-lang/rust/pull/23799).

So here a PR to removed this bound for `SendError<T>`, `TrySendError<T>` and `SendTimeoutError<T>`.

Combine three generalizer implementations

Fixes #111092
Fixes #109505

This code is a bit delicate and there were subtle changes between them, so I'll leave inline comments where further inspection is needed.

Regarding this comment from #109813 -- "add tests triggering all codepaths: at least the combine and the const generalizer", can't really do that now, and I don't really know how we'd get a higher-ranked const error since non-lifetime binders doesn't *really* support `for<const ..>` (it errors out when you try to use it).

Rollup merge of #111578 - Zoxc:query-macro-move, r=cjgillot
Move expansion of query macros in rustc_middle to rustc_middle::query

This moves the expansion of `define_callbacks!` and `define_feedable!` from `rustc_middle::ty::query` to `rustc_middle::query`.

This means that types used in queries are both imported and used in `rustc_middle::query` instead of being split between these modules. It also decouples `rustc_middle::ty::query` further from `rustc_middle` which is helpful since we want to move `rustc_middle::ty::query` to the query system crates.

Rollup merge of #111525 - scottmcm:slice-position-tweak, r=Mark-Simulacrum
Stop checking for the absence of something that doesn't exist

A couple of codegen tests are doing
```
// CHECK-NOT: slice_index_len_fail
```

However, that function no longer exists: [the only places](https://github.com/search?q=repo%3Arust-lang%2Frust+slice_index_len_fail&type=code) it occurs in the repo are in those tests.

So this PR updates the tests to check for the absense of the functions that are actually used today to panic for out-of-bounds indexing.

Don't claim `LocalKey::with` prevents a reference to be sent across threads

The documentation for `LocalKey` claims that `with` yields a reference that cannot be sent across threads, but this is false since you can easily do that with scoped threads. What it actually prevents is the reference from outliving the current thread.

Another proposed change in the same vein as #111492 trying to get rid of some clones.

This adds a TokenStream helper function so that rustdoc can directly get a chunks iterator over the underlying token trees so that it no longer needs the clones and vec.

Fix the `FileEncoder` buffer size.

It allows a variable size, but in practice we always use the default of 8192 bytes. This commit fixes it to that size, which makes things slightly faster because the size can be hard-wired in generated code.

The commit also:
- Rearranges some buffer capacity checks so they're all in the same form (`x > BUFSIZE`).
- Removes some buffer capacity assertions and comments about them. With an 8192 byte buffer, we're not in any danger of overflowing a `usize`.

e52794decd Don't try to eat non-existent decimal digits.
After seeing a `0`, if it's followed by any of `[0-9]`, `_`, `.`, `e`,
or `E`, we consume all the digits. But in the `.`, `e` and `E` cases
this is pointless because we know there aren't any digits.
