Structured suggestion for extern crate foo when foo isn't resolved in import

Browse Source 
When encountering a name in an import that could have come from a crate that wasn't imported, use a structured suggestion to suggest `extern crate foo;` pointing at the right place in the crate.

When encountering `_` in an import, do not suggest `extern crate _;`.
