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__.

int128: optimize and add test cases

For add, the carry only requires checking one of the arguments.
For sub and neg, we can similarly optimize computation of the
carry.

For ge, we can just do lexicographic order.
