I think there is value in optimizing relocation scanning. For some workload lld's pass takes 2.x time as mold's.
`InputSectionBase::relocations` takes some time but other checks contribute to the other slowdown.

We probably need to be more aggressive and possibly moving more relocation scanning into arch-specific `ELF/Arch/*.cpp`.
