[PATCH] D152840: [ELF] A new code layout algorithm for function reordering [3a/3]

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I have also explained that `SmallVector<*, 0>`  is preferred in lld/ELF code, so I have a `vector => ArrayRef` refactoring.
We should also get rid of `buildCallGraph`, which uses a number of output parameters, while the function can just be inlined into `apply*` (to be renamed).
