As far as I can tell, when the Awesome Bar shows a "Visit" link, we do not initiate a speculative connection to the site.

e.g.
The user types in what could be a url: https://www.somewebsite.com
The Awesome Bar shows the " -- Visit" link, but from looking at profiles we don't initiate the speculative connection until after the user hits return.

A performance profile captured before return is pressed (we only connect to google for search results)

The improvements would depend on the time to establish the connection to the host (including network environment), but if we made the speculative connection it could save about 60ms at the 70th percentile, looking at http page open to first sent

We should consider this once we're fairly sure the user is typing in a URL.
