Infer from arrows from usage. (#28832)
* Infer from arrows from usage.

Previously only function expressions were, and only those with an easily
accessible name. Now any arrow function or function expression will
infer from usage.

* remove isApplicableFunctionForInference

*all* functions are applicable for inference now.
