[issue2493] Remove unused constants from optimized code objects

Raymond Hettinger <[EMAIL PROTECTED]> added the comment: The issue with unused constants is an artifact of the peepholer running after the bytecode generation phase. When constant folding was written, I intentionally left-out a step to remove unused constants because of the code complexity, t
