I spent a bit more time cleaning a few things up in this. With all the
complexity from the extra fields, I felt that a round of adjusting the
"double" types so they use the "Cardinality" typedef where appropriate
was in order. costsize.c isn't very good at doing that, but I didn't
see that as a reason to make the problem worse. The only other change
was in explain.c where I added a local "Memoize *" variable rather
than casting the "plan" variable to the subclass type in each usage.

I understand not everyone got what they wanted here, but I hope what's
been added is ok for the majority of people.

Thanks for working on this Ilia and Lukas.
