[PATCH] D71959: [PassManagerBuilder] Remove global extension when a plugin is unloaded

[Elia Geretto via Phabricator via llvm-commits]

EliaGeretto updated this revision to Diff 235512.
EliaGeretto added a comment.

I have added comments to explain the reason of some of the changes and added an assert so that, if the `removeGlobalExtension` function is called with an invalid ID, the error will be more noticeable.

Please, let me know if you think the comments are clear enough.
