For backports whose _author_ equals the _committer_ of the original commit then the bots should add the label "original-committer". This helps reviewers on non-clean backports because if I can quickly see that the the original committer was the one doing the backport (which increases confidence that the backport is correct).

Note that we need to compare the _author_ of the backport to the _committer_ of the original commit. This is for the cases when a committer sponsors a patch from a non-OpenJDK and then backports the resulting commit. Furthermore the original committer is the one responsible for the original commit (since it was the person who issued the /integrate command).
