Why not just AutocompleteMatch::IsSearchType()? I also don't see why we need to
keep the "from_search_provider" check.

Please also add a test of some sort.

Sreeram: do you have any ideas for how to write a test for this that won't be
flaky?  Unless we have a way to mock out stuff and write a proper test, I think
the test will be almost certainly be flaky.

[sreeram, 2013/04/17 01:29:14]

How about something like this:
    SetOmniboxText("foo");
    instant()->SetSuggestions(a nav suggestion);
    GetBoolFromJS(nativeSuggestions[0].is_search, &value);
