Test leaking of BinaryHeap Drain iterators Add test cases about forgetting the `BinaryHeap::Drain` iterator, and slightly fortifies some other test cases. Consists of separate commits that I don't think are relevant on their own (but I'll happily turn these into more PRs if desired).
…piler-errors Remove `iter::Empty` hack `iter::Empty` uses a newtype to work around `#![feature(const_fn_fn_ptr_basics)]`, which has been stable since 1.61.0.
…-errors Fix `unused_must_use` warning for `Box::from_raw`
…tch-implementation, r=compiler-errors Fix backoff doc to match implementation The commit 8dddb22 in the crossbeam-channel PR (rust-lang#93563) changed the backoff strategy to be quadratic instead of exponential. This updates the doc to prevent confusion.

Implement allow-by-default `multiple_supertrait_upcastable` lint The lint detects when an object-safe trait has multiple supertraits. Enabled in libcore and liballoc as they are low-level enough that many embedded programs will use them. r? `@nikomatsakis`
…trieb Fix `core::any` docs Thanks to ``@pbevin`` in rust-lang#106154 Closes rust-lang#106154 ``@rustbot`` labels +A-docs
…mpiler-errors Emit fewer errors on invalid `#[repr(transparent)]` on `enum` Fix rust-lang#68420.
Remove some totally duplicated files in `rustc_infer` I have no idea why or how I duplicated these files from `compiler/rustc_infer/src/infer/error_reporting/note.rs`, but I did by accident, and nothing caught it 🤦
