This reverts commit 9c2a91fb72.
Reason for revert: breaks google3 (b/237016312)
Original change's description:
> Account for @pragma("vm:entry-point") creating additional "root" libraries when partitioning the program into loading units.
>
> If a library contained an entry point but was not reachable from the root library, it was not assigned to any loading unit and caused a null dereference in gen_snapshot. This is not possible with the standalone embedder, but is possible in Flutter because it passes multiple sources to frontend_server. E.g., `--source dart_plugin_registrant.dart`.
