Auto merge of #119581 - Nadrieril:detangle-arena, r=compiler-errors
Exhaustiveness: remove the need for arena-allocation within the algorithm

After https://github.com/rust-lang/rust/pull/119688, exhaustiveness checking doesn't need access to the arena anymore. This simplifies the lifetime story and makes it compile on stable without the extra dependency.
