I did the original change to make negative integers use just LOAD_CONST, but I
don't think I changed what was generated for float literals. That could be
my memory going bad, though.
The code changed several times as people with more numeric-fu that myself
fixed all sorts of border cases. I've tried really hard to stay away from
the code generator since then. :-)
