[PATCH] qemu/int128: Re-shuffle Int128Alias members

[Richard Henderson <richard.henderson@linaro.org>]

Clang 14, with --enable-tcg-interpreter errors with

include/qemu/int128.h:487:16: error: alignment of field 'i' (128 bits)
  does not match the alignment of the first field in transparent union;
  transparent_union attribute ignored [-Werror,-Wignored-attributes]
    __int128_t i;
               ^
include/qemu/int128.h:486:12: note: alignment of first field is 64 bits
    Int128 s;
           ^
1 error generated.

By placing the __uint128_t member first, this is avoided.
