Changes to namespace metadata are not properly transferred to *ns* dynamic var
Description
A CLJS macro may want to access the metadata of the current ns via (meta ns).
Changes to the ns metadata are not reflected back the ns var when re-compiling a namespace, the metadata of the first compile will remain. This is due to the analyzer always calling create-ns but never updating the meta. It should probably be updated inside parse 'ns [1]. Clojure always resets the metadata via the ns macro.
One potential conflict is when a .clj and a .cljs file exist for the same namespace and both provide different metadata. Both platforms reseting the meta is probably not ideal, maybe we should vary-meta merge instead?
