Any::isNull check

When a method is specialized for values, Any::isNull can only return
"false", which means if(Any.isNull(o)) can only ever have one outcome --
the other code branch can be discarded by the compiler. I know it's too
early to talk about optimizations :-) but will javac be smart enough to
recognize this optimization? Is it on your list for the future?
