It's not entirely unreasonable.  The same thing happens on HPPA,
which is nominally a 32-bit architecture but the hardware requires
8-byte alignment of doubles (and maybe int64 too, I forget).
On newer Intel hardware it'd make sense to pad to avoid misaligned
fetches.

Anyway, we detect this directly based on the C compiler's behavior,
and you can't argue with the compiler about it.  Whatever it's
doing is right by definition.
