Floats in the constants section. What I'm thinking is that all constants
*except* integers go in the constants section, and we inject in the
instruction stream an offset in the constants section wherever we'd put
the constant. That way we can fix the alignments as appropriate if we have
to.
This needs doing for strings, and once we get fancier
(array/hash/list) constants we'll need it for them, too, so we might as
well go all the way now and be done with it. (This'll also make generating
the instruction stream a little easier and abstract out constants in
general in case we decide to do things completely differently at some
point)
