Introducing single for loop into clang_proto_fuzzer
Summary:
Created a new protobuf and protobuf-to-C++ "converter" that wraps the entire C++ code in a single for loop.
- Slightly changed cxx_proto.proto -> cxx_loop_proto.proto
- Made some changes to proto_to_cxx files to handle the new kind of protobuf
- Created ExampleClangLoopProtoFuzzer to test new protobuf and "converter"
