The compiler cannot infer the target type of "(. RecordName -prototype)" expressions

Question

Repro:

Place

`
(set! warn-on-infer true)

(defrecord Foo [])
`

anywhere in your source files, compile with {{:infern-externs true}}.

Expected:

Multiple warnings like:
- {{WARNING: Cannot infer target type in expression (. Foo -prototype)}}
- {{WARNING: Cannot infer target type in expression (. other__8838__auto__ -constructor)}}
- {{WARNING: Cannot infer target type in expression (. user/Foo -getBasis)}}

There are also warnings for {{(. cljs.core/List -EMPTY)}}, but this might be unrelated.
