Improve handling of malformed / dsc_extractor.bundle-processed binaries

Hi, I have found that these https://github.com/Vector35/workflow_objc/blob/master/Core/AnalysisProvider.cpp#L22-L23 two analyzers raise out-of-bound exceptions. Used `LaunchServices` binary extracted using https://github.com/keith/dyld-shared-cache-extractor from arm64 cache. Will dig into it tomorrow and update the ticket.
