  Log Message:
  -----------
  [ThinLTO] Skip opt pipeline and summary wrapper pass on empty modules (#120143)

Follow up to PR118508, to avoid unnecessary compile time for an empty
combind regular LTO module if all modules end up being ThinLTO only.

This required minor changes to a few tests to ensure they weren't empty.
