Tweak typed-count Usage.

Tweak typed-count Usage.

Tweak how the typed count is used in the HistoryQuickProvider so that a typed_count of 1 is considered when presenting results.
Adjusted usage of the three factors in RowQualifiesAsSignificant so that the comparison operations are the same.
Adjusted unit tests since the tweak to RowQualifiesAsSignificant changes the expected results just a bit.

BUG=77476
TEST=Adjusted unit tests.

George, would you please take a look at these changes and see if there is a
reason why the unit tests would fail on Win and Linux? I've built for Win here
and those HistoryQuickProviderTest unit tests all succeed. I'm stumped and
hoping something will leap out to you.

File chrome/browser/autocomplete/history_url_provider_unittest.cc (right):

chrome/browser/autocomplete/history_url_provider_unittest.cc:155:
HistoryQuickProvider::set_disabled();
That is a problem. HistoryQuickProvider's unit-tests are usually run later in
the same process by trybots, but HistoryQuickProvider is going to stay disabled.
That is why Linux and Windows bots are failing. One possibility is to add friend
helper class that disabled HistoryQuickProvider in constructor and disables in
destructor.

This is ready to review and is an M14 bug.
