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.
The Result can be expect-unwrapped directly. (clippy::ok_expect)
…x| Some(y)) (clippy::option_and_then_some)
…nd anything.
For example: `if let Some(_) = foo() {}` can be reduced to `if foo().is_some() {}` (clippy::redundant_pattern_matching)
… type. These were introduced since I last fixed most of these occurences. (clippy::clone_on_copy, clippy::single_char_pattern)

…t, r=oli-obk Pass correct place to `discriminant_switch_effect` PR rust-lang#69562, which fixed a bug that was causing clippy to ICE, mistakenly passed the place holding the *result* of `Rvalue::Discriminant` instead of the place holding its *operand* to `apply_discriminant_switch_effect` as the enum place. As a result, no effect was applied at all, and we lost the perf benefits from marking inactive enum variants as uninitialized. This PR corrects that mistake and adds a regression test to `mir-opt`. I fear that the regression test may prove too brittle; the test schema makes hard to test for the *absence* of certain kinds of MIR without exhaustively matching each basic block. r? @oli-obk
…=Dylan-DPC Add explanation for E0380 r? @Dylan-DPC
Use associated constants of integer types Take advantage of rust-lang#68952 in the interpreter and some nearby modules :)
Update macros.rs: fix documentation typo.
more clippy cleanups
* Don't use .ok() before unwrapping via .expect() on a Result.
* Use .map() to modify data inside Options instead of using .and_then(|x| Some(y))
* Use .as_deref() instead of .as_ref().map(Deref::deref)
* Don't use "if let" bindings to only check a value and not actually bind anything.
* Use single-char patter on {ends,starts}_with and remove clone on copy type.
