This patch adds binary id into profiles to easily associate binaries with the corresponding profiles. There is an RFC that discusses the motivation, design and implementation in more detail: https://lists.llvm.org/pipermail/llvm-dev/2021-June/151154.html Differential Revision: https://reviews.llvm.org/D102039
