We have a lot of very similarly named classes related to dealing with module debug info. This patch has NFC, it just renames some classes to be more descriptive (albeit slightly more to type). The mapping from old to new class names is as follows: Old | New ModInfo | DbiModuleDescriptor ModuleSubstream | ModuleDebugFragment ModStream | ModuleDebugStream With the corresponding Builder classes renamed accordingly.
