Will we be using this in non-omnibox contexts later?  If not we should probably
name it omnibox_history anyway to reflect its usage in this codebase; reading
the code as-is, it implies the omnibox is stealing and reusing some random
history icon from elsewhere in Chrome or something.

yes, BackForwardMenuModel should use it. And on osx,
browser/ui/cocoa/history_menu_bridge.mm. And if we could figure out a way to use
vector icons for favicons, chrome://history would use it too.
