I had to add `std::swap` to this list since otherwise
the test cases `libcxx/module_std.gen.py/module_std.sh.cpp` and `libcxx/module_std_compat.gen.py/module_std_compat.sh.cpp` failed.

I don't quite understand the modules build, though. Is this correct?

(Note that we now have both a `std::swap` and a `std::_LIBCPP_ABI_NAMESPACE::swap`. Not sure if that matters. I hope not 🤞 )
