// compilation but at the same time does not modify names of CGUs that were not
// affected by merging.

// CGU partitioning creates one CGU per module, so with 4 modules and codegen-units=3,
// two of the modules should be merged. We expect CGUs `aaa` and `bbb` to be merged
// (because they are the smallest), while `ccc` and `ddd` should stay untouched.
