If a C++ `struct Base` declares a method with a Clang attribute that Swift is able to import, and `struct Derived` inherits from `Base`, the method should get cloned from `Base` to `Derived` with its attributes. Previously we were only cloning one attribute at most due to a bug in `cloneImportedAttributes`. DeclAttributes is an intrusively linked list, and it was being made invalid while iterating over it: `otherDecl->getAttrs().add(attrs)` iterates over the list and calls `otherDecl->add(eachElement)`, which invalidates the iterator after the first iteration.
