Remove misleading target feature aliases
Fixes#100752. This is a follow up to #103750. These aliases could not be completely removed until rust-lang/stdarch#1355 landed.

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.
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.
(docs) Change "wanting" to "want"
Changing " If you’re wanting" to "If you want".
Wanting is not wrong, of course, but I think that "If you want" feels more natural to most readers.
Fix some misleading and copy-pasted `Pattern` examples
These examples were listed twice and also were confusable with doing a substring match instead of a any-of-set match.
Appease lints
Resolved an unnecessary drop warning that appeared when running the linkchecker. Some clippy warnings, too.
Edit: Well this fired up all the CI pipeline. I hope that's not a problem.
Simplify find_width_of_character_at_span.
This makes `find_width_of_character_at_span` simpler and more robust against bad spans.
Fixes (but does not close, per beta policy) https://github.com/rust-lang/rust/issues/111485
add util function to TokenStream to eliminate some clones
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.
Start node has no immediate dominator
Change the immediate_dominator return type to Option, and use None to
indicate that node has no immediate dominator.
Also fix the issue where the start node would be returned as its own
immediate dominator.
