We now have several bools about what the text in the omnibox actually is. 
Consider changing at least some of these to an enum, e.g.

enum OmniboxTextType {
  PERMANENT_TEXT,
  USER_TEXT,
  NON_INSTANT_TEMPORARY_TEXT,
  INSTANT_TEMPORARY_URL,
  INSTANT_TEMPORARY_SEARCH
}

Can I punt on this? @beaudoin's refactor should take care of this. Even if the
refactor calls for a large redesign, we can do parts of it (such as collapsing
related state variables into one) incrementally, quickly.

Sure.

   // When the user's last action was to paste, we disallow inline autocomplete
   // (on the theory that the user is trying to paste in a new URL or part of
   // one, and in either case inline autocomplete would get in the way).
