I can't seem to use `SmallVector` for `__llvm_profile_data` because many of its defined fields are const qualified and it needs an assignment operator definition. I'm able to use `std::remove_const`, but that feels kind of hack-y. Not sure if the best solution is to use `std::vector`, `std::remove_const`, or remove the const qualifiers in [InstrProfData.inc](https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/ProfileData/InstrProfData.inc).
