I recently came across the `<internal>` issue, and was just reminded of the presence of the patch. I am in favor of this change.

Currently we had 7 states: `nullptr, ObjKind, SharedKind, LazyObjKind, ArchiveKind, BitcodeKind, BinaryKind`.
With this change, we still have 7: `SyntheticKind, ObjKind, SharedKind, LazyObjKind, ArchiveKind, BitcodeKind, BinaryKind`.

A nice property is that `InputSectionBase::file` and `Symbol::file` will never be null.
