The case of NULL stream passed to stream functions was reported by StreamChecker. The same condition is checked already by StdLibraryFunctionsChecker and it is enough to check at one place. The StreamChecker stops now analysis if a passed NULL stream is encountered but generates no report. This change removes a dependency between StdCLibraryFunctionArgs checker and StreamChecker. There is now no more specific message reported by StreamChecker, the previous weak-dependency is not needed. And StreamChecker can be used without StdCLibraryFunctions checker or its ModelPOSIX option. Reviewed By: Szelethus Differential Revision: https://reviews.llvm.org/D137790
