…o BTreeMap::append)

For the attribute `FooBar` the parser is generally called `FooBarParser` and the kind is called `AttributeKind::FooBar`. This commit renames some cases that don't match that pattern. The most common cases: - Adding `Rustc` to the front of the parser name for a `rustc_*` attribute. - Adding `Parser` to the end of a parser name. - Slight word variations, e.g. `Deprecation` instead of `Deprecated`, `Pointer` instead of `Ptr`, `Stability` instead of `Stable`.
Previously this would sometimes just say "unexpected output ``", which was extremely unhelpful. The actual issue was that I had a `.jj` directory but not a `.git` directory, so it couldn't run `git submodule update.`
…ark-Simulacrum ptr::replace: make calls on ZST null ptr not UB See rust-lang#138351 for context. We made `ptr::read` and `ptr::write` not UB on ZST null pointers. This does the same with `ptr::replace`. Since we're just adding a branch on a constant, this should come at no runtime cost.
Fix doc link used in suggestion for pinning self Fixes rust-lang#147901 The old suggestion linked to a documentation page that [no longer exists](https://rust-lang.github.io/async-book/04_pinning/01_chapter.html#pinning-in-practice). Presumably, [this](https://rust-lang.github.io/async-book/part-reference/pinning.html) is the better place to link to now
…, r=Mark-Simulacrum `BTreeMap::merge` optimized This is an optimized version of rust-lang#151981. See [ACP](rust-lang/libs-team#739 (comment)) for more information on `BTreeMap::merge` does. CC @programmerjake. Let me know what you think of how I'm using `CursorMut` and `IntoIter` here and whether the unsafe code here looks good. I decided to use `ptr::read()` and `ptr::write()` to grab the value from `CursorMut` as `V` than `&mut V`, use it within the `conflict` function, and overwrite the content of conflicting key afterward. I know this needs some polishing, especially with refactoring some redundant looking code in a nicer way, some of which could probably just be public API methods for `CursorMut`. It does pass all the tests that I currently have for `BTreeMap::merge` (inspired from `BTreeMap::append`) though, so that's good.

What is this?This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.Comparing 11ad63a (parent) -> 58745ca (this PR) Test differencesShow 311 test diffsStage 1
Stage 2
Additionally, 227 doctest diffs were found. These are ignored, as they are noisy. Job group index
