[Mac] Trim Omnibox hints as field shrinks.

When user text doesn't fit with the full hint:
   "Type to search" hint goes away
   "Tab to search" condenses to "Tab"
   "Search Engine:" is truncated

http://crbug.com/20285
TEST=Type a sentence.  Resize window to see if type-hint goes away.
TEST=Type "google".  Resize window to see if tab-hint goes away.
TEST=Type "google" then TAB, then sentence.  Resize window to see if "Search Google:" is truncated.
TEST=In all cases, text should not scroll before truncation (though it might move as part of truncation).
