`INSTR_PROF_RAW_VERSION` is not bumped. It was bumped in the first revision of this patch if you looked at the history.

Somehow the binary ID change got pushed before this and it has been rolled back/forward several times in main.
The version is not updated to not cause unnecessary conflict with that patch.

Even if `INSTR_PROF_RAW_VERSION` is bumped, I think it is very likely your Rust downstream will observe an `if (GET_VERSION(Version) != RawInstrProf::Version)` error in llvm-profdata,
because from your description it seems you are likely mixing raw profile files produced by compiler-rt/lib/profile built at different commits.
