[PATCH] D84008: [DWARFYAML][WIP] Refactor emitDebugInfo() to make the length be inferred.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

The number of changed tests is large. Is it worth moving the `IO.mapOptional("Length", Unit.Length);` change to a separate patch to make the refactoring more focused? Thanks
