One thing we should consider though: since presumably the psABI has
max_align_t as 16-byte alignment on powerpc now, if we increase i386
should we also increase powerpc? Even though there's no type actually
depending on it? This also applies to powerpc64 too, I think, which is
an arch not being affected by time64 change.
