Sending this to the upload bots just cost me over an hour. This added lld
locally to the bots, but only on this try job. Future jobs then had this old
checkout of lld flying around that never got updated, and that led to test
failures.

Please don't use the upload bots for testing stuff that adds folders to the
checkout.
