Fix a corner case when following conditions are met in a single module: * Module A is imported in the current module * There exists a versioned `canImport` check for a module A * All `canImport` check within the module evaluated to false If all above conditions are met, swift-frontend will not received the version number from scanner, and it will be confused if version is either not available (thus a warning, and treat as true), or condition is not met (eval to false). Now make sure if when scanner tries to resolve `canImport`, it will record all instances that a module can be imported, or a version of the module is found. rdar://167784812
