O1 <https://reviews.llvm.org/owners/package/1/>, O2 <https://reviews.llvm.org/owners/package/2/> and O3 <https://reviews.llvm.org/owners/package/3/> appear to be the same for now. But in future, some
passes may be disabled at lower levels (e.g. O1 <https://reviews.llvm.org/owners/package/1/>). Hoping we can use
FileCheck prefixes for differences to avoid repeating the contents 3
times.
