Now that we've removed the inheritorID from objects, we can increase our inline storage for JSFinalObjects on 64-bit platforms by 1.

Looks like a slight win on v8-real (~7% on richards) and kraken (~2% on imaging-darkroom).

This is going to make our lives harder when we go back to shrink these objects later, since it will be harder to do so without causing a performance regression. :( I guess we'll need to fast-track being smart about predicting and/or responding to object size.
