When DISubprogram is being cloned, types belonging to its scope
must be cloned too. Otherwise, function-local types of the original
function are used in the cloned one, which may cause conflicts.

Additionally, when tracking function-local types in the DISubprogram
(via retainedTypes or enums fields), it seems reasonable to track
the clones as well.

It helps to tackle the crash encountered after committing
