Our current coverage pipeline has the following steps:

1. Read binary-id in each raw profile (`.profraw`) via using `llvm-profdata`
2. Fetch all the binaries that with the corresponding binary id
3. Merge all the raw profiles, and generate an indexed profile (`profdata`)
4. Generate a coverage report via using `llvm-cov` by providing all the fetched binaries and indexed profile.

We would like to simplify our coverage pipeline by using [[ debuginfod | https://sourceware.org/elfutils/Debuginfod.html ]] in `llvm-cov`.
When we include binary ids into indexed profiles and start using `debuginfod` in `llvm-cov`, our coverage pipeline can look like this:

1. Merge all the raw profiles, and generate an indexed profile (`profdata`)
2. Generate a coverage report via using `llvm-cov` by providing only an indexed profile. `llvm-cov` is going to read all the binary ids from an indexed profile, and fetch them from the `debuginfod` server.
