The motivation is to suppresses false use-after-free reports that occur when calling std::list::pop_front() or std::list::pop_back() twice. The analyzer does not reason about the internal invariants of the list implementation, so just do not report any of warnings in std::list. Fixes radar://14317928. llvm-svn: 185609
