It can be some other loop metadata. 

The test inlined-loop-metadata.ll provides an example:
```
...
br i1 %13, label %middle.block, label %vector.body, !llvm.loop !15
...
!10 = !DILocation(line: 4, scope: !8)
!15 = distinct !{!15, !10, !16, !17}
!16 = !DILocation(line: 6, scope: !8)
!17 = !{!"llvm.loop.isvectorized", i32 1}
```
