Use __SIZEOF_INT128__ to test __int128 presence
Previously we tested whether a handful of preprocessor variables indicating certain 64 bit platforms, but this does not work for other 64 bit targets which have support for __int128 in C compiler. Use the __SIZEOF__INT128__ preprocessor variable instead. This variable gets set to 16 by gcc and clang for every target where __int128 is supported.
