[clang] [NFC][clang] Correct bswapg test to work when int128 is not available (PR #168261)

[Oliver Hunt via cfe-commits]

https://github.com/ojhunt created https://github.com/llvm/llvm-project/pull/168261

This updates the test to avoid inclusion of int128 bswapg tests on targets that don't support int128 at all.

This fixes failures introduced by #162433
