PR rust-lang#69562, which fixed a bug that was causing clippy to ICE, passed the place for the *result* of `Rvalue::Discriminant` instead of the *operand* to `apply_discriminant_switch_effect`. As a result, no effect was applied at all, and we lost the perf benefits from marking inactive enum variants as uninitialized.
For all of the methods that pick off the first or last element, we can use subslice patterns to implement them directly, rather than relying on deeper indexing function calls. At a minimum, this means the generated code will rely less on inlining for performance, but in some cases it also optimizes better.
Use .next() instead of .nth(0) on iterators.
Rename DefKind::Method and TraitItemKind::Method r? @eddyb, @Centril, or @matthewjasper cc rust-lang#69498 rust-lang#60163
