Aurlien reported that clang's build was broken by the recent fix
845fb846c7 ("BUG/MEDIUM: stick-tables: properly mark stktable_data
as packed"), because it now wants to use a helper for some atomic
ops (to increment std_t_uint). While this makes no sense to do
something that slow on modern architectures like x86 and arm64 which
are fine with unaligned accesses, we actually we can simply mark the
struct as aligned to its smallest element which is 32-bit (but still
packed). With this, it was verified that it is enough for clang to
see that its 32-bit operations will always be aligned, while making
64-bit operations safe on 64-bit platforms that do not support unaligned
accesses.
This should be backported wherever the patch above is backported.
