This instruction appeared in CI [here](https://github.com/bernhardu/llvm-project/actions/runs/16751204175/job/47421639002#step:7:1441),
while trying to run the Windows ASan tests for i686 and amd64.

```
==5976==interception_win: unhandled instruction at 0x7ff7662a48d4: 0f 29 74 24 30 0f 28 f0
==2188==interception_win: unhandled instruction at 0x7ff7dc8848d4: 0f 29 74 24 30 0f 28 f0
```

Unfortunately this did not show up in any other run before or afterwards,
so I cannot say from which file this instruction originates from.
