[PATCH] D33655: [Cloning] Take another pass at properly cloning debug info

[Gor Nishanov via Phabricator via llvm-commits]

GorNishanov added a comment.

Looks good from a coroutine side. Though I am not fluent in DebugInfo to LGTM the whole change.

One comment about "ModuleLevelChanges" parameter.
Is the description of that parameter accurately captures its purpose?

Namely:
/// If ModuleLevelChanges is false, VMap contains no non-identity GlobalValue
/// mappings.
