Rollup merge of #37250 - liigo:rustdoc-unsafe-fns, r=steveklabnik
rustdoc: mark unsafe fns in module page with superscript icons Note: I'v changed the mark style. Now use superscript ⚠(U+26A0) (the old one is '[Unsafe]' literal). Basically per https://botbot.me/mozilla/rust-docs/2016-10-19/?msg=75112017&page=1 ![unsafe-fn-icon](https://cloud.githubusercontent.com/assets/346530/19633650/7f6e1eea-99e6-11e6-8d09-31aec83e46a5.png) ![unsafe-fn](https://cloud.githubusercontent.com/assets/346530/19472050/39daded2-9558-11e6-9148-3cb12afd1c9a.png)
