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.  :-)
