Negate suggestions when needed in `bool_assert_comparison`
changelog: none assuming this gets into the same release as #10218Fixes#10291
r? `@dswij`
Thanks to `@black-puppydog` for spotting it early
Rename `replace_bound_vars_with_*` to `instantiate_binder_with_*`
Mentioning "binder" rather than "bound vars", imo, makes it clearer that we're doing something to the binder as a whole.
Also, "instantiate" is the verb that I'm always reaching for when I'm looking for these functions, and the name that we use in the new solver anyways.

Make `derive_const` derive properly const-if-const impls
Fixes#107774Fixes#107666
Also fixes rendering of const-if-const bounds in pretty printing.
r? ```@oli-obk``` or ```@fee1-dead```
Change `arena_cache` to not alter the declared query result
This makes the return types a bit clearer, limiting `arena_cache`'s effect to just the computation side. It also makes it easier to potentially remove `arena_cache`.
r? ```@cjgillot```
Update strip-ansi-escapes and vte
This updates strip-ansi-escapes from 0.1.0 to 0.1.1 (and consequently vte).
Changes: https://github.com/luser/strip-ansi-escapes/compare/0.1.0...0.1.1
The only change really is updating vte which fixes some parsing issues (and drops the vendored source size by several megabytes).
Closes#107708
Treat Drop as a rmw operation
Previously, a Drop terminator was considered a move in MIR. This commit changes the behavior to only treat Drop as a mutable access to the dropped place.
In order for this change to be correct, we need to guarantee that
1. A dropped value won't be used again
2. Places that appear in a drop won't be used again before a
subsequent initialization.
We can ensure this to be correct at MIR construction because Drop will only be emitted when a variable goes out of scope, thus having:
* (1) as there is no way of reaching the old value. drop-elaboration
will also remove any uninitialized drop.
* (2) as the place can't be named following the end of the scope.
However, the initialization status, previously tracked by moves, should also be tied to the execution of a Drop, hence the additional logic in the dataflow analyses.

Implement cursors for BTreeMap
See the ACP for an overview of the API: https://github.com/rust-lang/libs-team/issues/141
The implementation is split into 2 commits:
- The first changes the internal insertion functions to return a handle to the newly inserted element. The lifetimes involved are a bit hairy since we need a mutable handle to both the `BTreeMap` itself (which holds the root) and the nodes allocated in memory. I have tested that this passes the standard library testsuite under miri.
- The second commit implements the cursor API itself. This is more straightforward to follow but still involves some unsafe code to deal with simultaneous mutable borrows of the tree root and the node that is currently being iterated.
fix(suspicious_to_owned): use span_suggestions to suggest both intents
fixes#10294
changelog: [`suspicious_to_owned`]: suggestions now produce valid Rust code
Remove astconv usage in diagnostic
Fixes#107775
Location of the test sucks, I know, but I needed to put it somewhere 😓
The issue here is that the root cause of the issue has nothing to do with what's being tested, so I couldn't really give it a better name. Oh well.
rustdoc: use a newline instead of `<br>` to format code headers
Since these elements now use `white-space: pre-wrap` since #107615, it's fine to use newlines for formatting, which is smaller and a bit less complicated.
Rename `PointerSized` to `PointerLike`
The old name was unnecessarily vague. This PR renames a nightly language feature that I added, so I don't think it needs any additional approval, though anyone can feel free to speak up if you dislike the rename.
It's still unsatisfying that we don't the user which of {size, alignment} is wrong, but this trait really is just a stepping stone for a more generalized mechanism to create `dyn*`, just meant for nightly testing, so I don't think it really deserves additional diagnostic machinery for now.
