We're not going to stabilize Option::{unwrap_none, expect_none}. (See #62633.) This removes the usage of those unstable methods from compiler/.

Could you avoid putting anything with side effects into asserts?
Asserts may be casually removed or turned into debug asserts, so running meaningful code in them always triggers some level of alarm.

Done.

I added try_insert (#82764) and assert_matches (#82770) to make it a bit nicer.

Could you avoid evaluating things twice as well?

foo(map[key]);
assert_eq!(map[key], expected);

=>

let value = map[key];
foo(value);
assert_eq!(value, expected);

It's not immediately obvious whether it's something cheap like array access or more expensive like BTreeMap search in each specific case.

Remove unwrap_none/expect_none from compiler/.

We're not going to stabilize `Option::{unwrap_none, expect_none}`. (See rust-lang#62633.) This removes the usage of those unstable methods from `compiler/`.
