tests/test-int128: Don't use __noclone__ attribute on clang
clang doesn't support the __noclone__ attribute and emits a warning about it. Fortunately clang also implements a mechanism for asking if a particular attribute is implemented; use it. We assume that if the compiler doesn't support __has_attribute() then it must be GCC and must support __noclone__.
