r? `@oli-obk`

I tried to follow your comment about what to do [here](rust-lang/rust#121672 (comment)). However, I'm totally unfamiliar with the code so far (this is my first contribution touching compiler code), so I apologize in advance if I did something stupid 😅

In particular, I'm not sure I use the _correct_ source scope to look for inline data, as there is a whole `IndexVec` of them. My changes definitely did something, as can be seen by the added ui test. However, the result is not as anticipated in the issue:
```
LL |     let cell = std::cell::UnsafeCell::new(data);
   |                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ value moved from here
```
instead of
```
LL |     let cell = std::cell::UnsafeCell::new(data);
   |                                           ^^^^ value moved from here
```
raising my suspicion that maybe I got the wrong source scope.
