Self-approval in order to test this sooner.

Ah, I think I got it. The problem is that on the buildbot the files are printed in different order that on my machine, so main.cc is the last one in the list. Hm, how can I handle that...

 Instructions for regenerating the test:
 
 clang -mllvm -enable-name-compression=false -fprofile-instr-generate -fcoverage-mapping main.cc -o main
 
 LLVM_PROFILE_FILE="main.raw" ./main
 llvm-profdata merge main.raw -o main.profdata
 llvm-cov convert-for-testing ./main -o ./main.covmapping
