-/// Connect atoms with layout-{before,after} edges. It usually serves two
-/// purposes.
-///
-///   - To prevent atoms from being GC'ed (aka dead-stripped) if there is a
-///     reference to one of the atoms. In that case we want to emit all the
-///     atoms appeared in the same section, because the referenced "live" atom
-///     may reference other atoms in the same section. If we don't add layout
-///     edges between atoms, unreferenced atoms in the same section would be
-///     GC'ed.
-///   - To preserve the order of atmos. We want to emit the atoms in the
-///     same order as they appeared in the input object file.
