This won't work if custom user data dirs are in use, will it?  I think the right
thing to do at uninstall is to iterate over all autolaunch entries and remove
any that point to the Chrome executable that's being uninstalled.

Hmm... It will not, but I'd rather disable this feature for --user-data-dir than
iterate over keys and remove random ones that point to a chrome executable...
(which would be a shame). 

However, I don't think this is a use case we should worry about. People who use
--user-data-dir know how to remove registry keys (and besides, a stray Run key
is harmless).

Iterate and delete will be required if/when the feature supports anything other
than kInitialProfile, as the uninstaller doesn't know anything about what
profiles may have been created.

Also, deleting a profile must result in the removal of its corresponding
autolaunch key.  Can the initial profile be deleted?
Leaving stray data laying around on users machines is bad.  How is a user
expected to know to look in the Run key to clean up behind Chrome?
