add support for __int128
There is already support for __int128_t & __uint128_t but not yet
for GCC's __int128.
This patch add support for it and a couple of test cases.
Note: it's slightly more tricky that it look because contrary to
'__int128_t', '__int128' is not an exact type (it can still receive
the 'unsigned' or 'signed' specifier).
