One more thought to simplify the code here. We could consider adding Profile*
argument to CreateGCMDriverDesktop helper function that will figure out the
right path and IdentityProvider based on whether profile is null or not.

[bartfab (slow), 2014/06/04 11:00:48]

I think it would be be better to not introduce a |Profile| argument if
CreateGCMDriverDesktop() can work without a |Profile| as well. Also, the
identity provider requirement is going away soon anyway, so all of the code that
deals with it will be removed soon anyway.
