        Simplified null-ish JSValues.
        
        Replaced calls to noValue() with calls to JSValue() (which is what
        noValue() returned). Removed noValue().
        
        Replaced almost all uses of jsImpossibleValue() with uses of JSValue().
        Its one remaining use is for construction of hash table deleted values.
        For that specific task, I made a new, private constructor with a special
        tag. Removed jsImpossibleValue().
        
        Removed "JSValue()" initialiazers, since default construction happens...
        by default.
