Would it make sense to name it AutocompleteController (without Android, since it
is already in the android/ directory?

We use the actual chrome/browser/autocomplete AutocompleteController within this
class -- if we name this class the same, we will have to use namespaces in the
code to differentiate. This way it's more clear which class we are referring to
and it seems to be what we have done in other places where the names are the
same.
