There has to be a better place for this.  This sort of very specific method
doesn't belong in a general class such as InfoBarManager.  It's doubly
concerning that major platforms like views don't even use an infobar for this. 
It feels like the entire idea that there is a specific "autofill infobar"
shouldn't be in components/.

I'm also looking at the stuff added to AutofillCCInfoBarDelegate and wondering
if it's ever going to be used outside this platform-specific AutofillInfoBar. 
I'm beginning to think that class shouldn't be changed either, and we should
either have some kind of subclass or some entirely unrelated class to handle the
Android-specific needs here.

Created components/autofill/core/browser/autofill_save_card_infobar_mobile.h
with CreateSaveCardInfoBarMobile() function. It's defined only on iOS and
Android.
Moved mobile-specific modifications into AutofillSaveCardInfoBarDelegateMobile.

   // TODO(droger): Absorb these methods back into their callers once virtual
   // overrides are removed (see http://crbug.com/354380).
