LOG: [LTO] Replace anonymous namespace with static functions (NFC).

Only class declarations should be inside anonymous namespaces
(https://llvm.org/docs/CodingStandards.html#anonymous-namespaces)

Instead of using a anonymous namespace, just mark the functions in it as
static (some of them already were).

This simplifies the diff for D94486.
