Don't read fields of a misaligned ExpandedObjectHeader or AnyArrayType.
UBSan complains about this. Instead, cast to a suitable type requiring
only 4-byte alignment. DatumGetAnyArrayP() already assumes one can cast
between AnyArrayType and ArrayType, so this doesn't introduce a new
assumption. Back-patch to 9.5, where AnyArrayType was introduced.
