fixed https://github.com/clojure/clojurescript/commit/b5147bfeb1e8034e93014e35bb27c9fb4d9c10de

Attached patch with `disallowing-ns*` instead of a `:top-level` in the analyzer environment.

Attached patch with proposed implementation and tests.

Turns out we don't need custom resolution. Google Closure doesn't care if we add definitions to some other namespace.

This isn't just for scripts. There are other typical patterns that needs this like data literal files. Having a significant difference from Clojure here when we can in fact largely close the gap is and has always been undesirable. The outlined plan does not introduce any significant complexity - with cljs.user subnamespaces (these should have stable names not random ones btw) + custom resolve for cljs.user vars we will produce code that is perfectly usable for both runtime dev and advanced compilation.
