bors c62b732724 Auto merge of #135709 - lqd:bring-back-len, r=compiler-errors
Temporarily bring back `Rvalue::Len`

r? `@compiler-errors` as requested in https://github.com/rust-lang/rust/issues/135671#issuecomment-2599580364

> However, in the mean time, I'd rather we not crunch trying to find and more importantly validate the soundness of a solution 🤔

Agreed. To fix the IMO P-critical #135671 for which we somehow didn't have test coverage, this PR temporarily reverts:
- https://github.com/rust-lang/rust/pull/133734
- its bugfix https://github.com/rust-lang/rust/pull/134371
- https://github.com/rust-lang/rust/pull/134330

I added the few samples from that issue as a test, but we can add more in the future, in particular it seems `@steffahn` [will work on that](https://github.com/rust-lang/rust/issues/135671#issuecomment-2599714354).

Fixes #135671. And if we want to land this, it should also be nominated for beta backport.
