If a C++ object already has a JS wrapper, we don't need to go through the expensive type checks to figure out which kind of wrapper to create. Instead, just return the wrapper we already have! This gives a noticeable increase in smoothness on Acid3, where ~10% of CPU time was previously spent doing RTTI type checks in wrap(). With these changes, it's down to ~1%.
