Depends on D112160 <https://reviews.llvm.org/D112160>

This adds the new options `--call-graph-profile-sort` (default), `--no-call-graph-profile-sort` and `--print-symbol-order=`. If call graph profile sorting is enabled, reads __LLVM,__cg_profile sections from object files and uses the resulting graph to put callees and callers close to each other in the final binary via the C3 clustering heuristic.
