I think this needs a separate option HelperLoaderMode::Global. As I understand it from #7599, the requirement is:

1. Do NOT generate import / require.
2. Create a unique symbol name for the helper function.
3. Helper usage includes that symbol name e.g. _defineProperty(...).
4. Return object mapping symbol names to import paths.

This is different from the existing modes:

• Runtime mode inserts import/require.
• External mode doesn't create a symbol name for each helper - it outputs babelHelpers.defineProperty(...) not _defineProperty(...).

HelperLoaderMode::Global should use TraverseCtx::generate_uid_name to generate symbol name, instead of generate_uid_in_root_scope. This will create a unique name and add it to set of used UIDs so it doesn't get used again, but will NOT create a binding. The IdentifierReference returned should be unbound (i.e. global reference).

Also see #7599 (comment). I'm not completely sure this is going to solve the root problem.
