Is there no better way to do this?  I'm not sure why this has to be added only
for this one particular infobar when the other infobar types have gotten by
without it.

[please use gerrit instead, 2016/01/12 00:47:25]

Another way is to add detail_icon(), detail_label(), detail_sub_label(),
legal_message_lines()... to confirm_infobar.h. However, infobar owners (e.g.
Peter) might disagree on whether confirm_infobar.h should contain
mobile-specific elements.

Ended up making an autofill_save_card_infobar_mobile.h file with
CreatSaveCardInfoBarMobile() function, which is defined in iOS and Android
specific files.

+  virtual scoped_ptr<infobars::InfoBar> CreateAutofillCCInfoBar(
+      scoped_ptr<autofill::AutofillCCInfoBarDelegate> delegate) = 0;

  protected:
   // Notifies the observer in |observer_list_|.
   // TODO(droger): Absorb these methods back into their callers once virtual
   // overrides are removed (see http://crbug.com/354380).
   virtual void NotifyInfoBarAdded(InfoBar* infobar);
   virtual void NotifyInfoBarRemoved(InfoBar* infobar, bool animate);
