There's some prior art in [`func.blocks.arc.pass.mm`](https://github.com/llvm/llvm-project/blob/e953623f50929dfa038d4d7d234f9822d63dc729/libcxx/test/libcxx/utilities/function.objects/func.blocks.arc.pass.mm) for depending on the Blocks runtime in a test. Not sure if it's also okay to depend on the host libobjc similarly.
