A previous patch added the ability for us to tell if types were forcefully completed. This patch adds the ability to see which modules have forcefully completed types and aggregates the number of modules with forcefully completed types at the root level. We add a module specific setting named "debugInfoHadIncompleteTypes" that is a boolean value. We also aggregate the number of modules at the root level that had incomplete debug info with a key named "totalModuleCountWithIncompleteTypes" that is a count of number of modules that had incomplete types.
