Implements `trim_prefix` and `trim_suffix` methods for both `slice` and `str` types which remove at most one occurrence of a prefix/suffix while always returning a string/slice (rather than Option), enabling easy method chaining.

rewrite `optimize` attribute to use new attribute parsing infrastructure r? `@oli-obk` I'm afraid we'll get quite a few of these PRs in the future. If we get a lot of trivial changes I'll start merging multiple into one PR. They should be easy to review :) Waiting on rust-lang#138165 first
…r=ChrisDenton,tgross35 Implement send_signal for unix child processes Tracking issue: rust-lang#141975 There are two main differences between my implementation and the Public API section of the tracking issue. ~First, `send_signal` requires a mutable reference, like `Child::kill`.~ Second, `ChildExt` has `Sealed` as a supertrait, bringing it more in line with other extension traits like `CommandExt`. try-job: `dist-various*` try-job: `test-various*`
Add `trim_prefix` and `trim_suffix` methods for both `slice` and `str` types. Implements `trim_prefix` and `trim_suffix` methods for both `slice` and `str` types, which remove at most one occurrence of a prefix/suffix while always returning a string/slice (rather than Option), enabling easy method chaining. ## Tracking issue rust-lang#142312 ## API ```rust impl str { pub fn trim_prefix<P: Pattern>(&self, prefix: P) -> &str; pub fn trim_suffix<P: Pattern>(&self, suffix: P) -> &str where for<'a> P::Searcher<'a>: ReverseSearcher<'a>; } impl<T> [T] { pub fn trim_prefix<P: SlicePattern<Item = T> + ?Sized>(&self, prefix: &P) -> &[T] where T: PartialEq; pub fn trim_suffix<P: SlicePattern<Item = T> + ?Sized>(&self, suffix: &P) -> &[T] where T: PartialEq; } ``` ## Examples ```rust // Method chaining assert_eq!(" <https://example.com/> ".trim().trim_prefix('<').trim_suffix('>').trim(), "https://example.com/"); // Slices let v = &[10, 40, 30]; assert_eq!(v.trim_prefix(&[10]), &[40, 30][..]); ``` ## ACP Originally proposed in rust-lang/libs-team#597

Reason about borrowed classes in CopyProp. Fixes rust-lang#141122 The current implementation of `CopyProp` avoids unifying two borrowed locals, as this would change the result of address comparison. However, the implementation was inconsistent with the general algorithm, which identifies equivalence classes of locals and then replaces all locals by a single representative of their equivalence class. This PR fixes it by forbidding the unification of two *classes* if any of those contain a borrowed local.
vec_deque/fmt/vec tests: remove static mut More rust-lang#125035. r? `@tgross35`
Reduce uses of `hir_crate`. I tried rebasing my old incremental-HIR branch. This is a by-product, which is required if we want to get rid of `hir_crate` entirely. The second commit is a drive-by cleanup. It can be pulled into its own PR. r? ``@oli-obk``
