This removes some churn when adding new diagnostic cases to test files (where previous to this change the newly added newline would cause the previous diagnostic CHECKs to be updated including changes to the line number because the CHECK for the blank line meant an extra line between CHECK and source line). A few alternatives discussed here: https://discord.com/channels/655572317891461132/655578254970716160/1329573358475673723 --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
