JS try/catch is more dynamic than Clojure

[borkdude]

E.g. (try 1 (catch (if (odd? 3) js/Number js/Error) e 2))
Instead of resolving the class at analysis time, we should probably just eval the expression after the catch and then bind it?
The resolving now is also special cased on "js" which is probably wrong if you explicitly use the {:classes {'js js/window}} option.
