Description

Investigate the impact of cljs.spec on :advanced builds.

Currently all specs are kept in the (private) cljs.spec/registry-ref atom. This atom is not understood by the Closure Compiler and cannot be eliminated as dead code. So even if specs are not used in "production" they still bloat the generated JS size. Some specs may be used at runtime and cannot not be removed, the gen parts however are probably never required in :advanced builds and should be omitted somehow.

In a test build (with 1.9.93) this adds 11kb (102kb vs 91kb) as soon as cljs.spec is :require'd somewhere and goes up with each defined spec.
