And that's *still* not right, because whether a type is pass-by-value
has again got exactly 0 to do with what the bits look like on disk.

The only 32-vs-64-bit difference that has any impact on the on-disk
layout is MAXALIGN, which tends to be different in the two cases
(though there are exceptions).
