How come we're still using an ifdef for this?

Also how do we wind up here exactly?  Is this just for the 200 case, or also the
302 case (i.e. are the calls to show the one-click bar each covering mutually
exclusive cases, or is there some overlap?)

Not all platforms use one-click sign in, like android and chromeos for example. 
So this feature is turned on only for desktop.

This case handles 200s, its the OnResponseStarted() callback.  The 302 is
handled just below, line 372, in the OnRequestRedirected() callback.

+  // See if the response contains the Google-Accounts-SignIn header.  If so,
+  // then the user has just finished signing in, and the server is allowing the
+  // browser to suggest connecting the user's profile to the account.
