Another update. This adds a rudimentary implementation of 8.5.3 
(reference binding) to TryCopyInitialization. This allows references to 
bind to less cv-qualified versions of the same type as well as to 
subclasses of the reference type, which is a considerable improvement 
over the current situation. Subclass checking is not as stringent as it 
should be.
This isn't in the actual initialization code yet, but it works for 
static_cast and should work for argument passing.
