Optimal structure field ordering

[Brian T. Schellenberger]

So put the *most commonly used* fields early to optimize access and sort
large-to-small to optimize space.  Tradeoffs between these two considerations
vary widely.  But especially if you have one field you use a lot, try to put
it first regardless of size; the first field has an offset of zero, ans this is
more efficiently accessed on (to put in mildly) a wide variety of machines.
