please review this patch to enable caching of getCanonicalName and 
getSimpleName, repeated calls of which has been reported to be a 
bottleneck. The caching improves performance of these methods by up to 20x.

Rather than adding new fields to Class itself, which would have 
footprint implications on classes, we can piggy-back on 
Class$ReflectionData object.
