I think it's fine for Clang to print suffixes that are only accepted with certain flags. Presumably, you should never get an IntegerLiteral of type __int128_t unless you're in a dialect that supports parsing it.

… except that we cheat when we're building template arguments, because it was convenient. That cheating could be eliminated by encoding integer literal values directly within SubstNonTypeTemplateParmExpr.
