Fix bug where lazy pairs used excessive amounts of memory

environment once rather than each time a pair is created.

Exercise 4.34: Pretty printing of lazy pairs
...
This change makes cons a special form that returns a tagged
procedure. This tag is used to distinguish it from normal procedures
when printing out the pair. Apply is modified to skip over the tag
and apply the procedure as normal.

Exercise 4.33: transform quoted pairs into cons for lazy lists
...
This turns a quoted expression into one or more conses. If these are
defined to be the lazy versions, then we will get lazy lists.

Use lazy-eval rather than actual-value for stored programs
...
We don't care about the actual value, because these are just defines,
so we only need their side effects.

This also requires a move for the non-analyzing evaluator (it was
