[access-control] non same-origin to same-origin redirect

Since Jonas didn't e-mail about this I thought I would. Say  
http://x.example/x does a request to http://y.example/y.  
http://y.example/y redirects to http://x.example/y. If this request were  
to use the Access Control specification the algorithm would have a status  
return flag set to "same-origin" and a url return flag set to  
http://x.example/y. XMLHttpRequest Level 2 would then attempt a same  
origin request to http://x.example/y.

For simplicity and to err on the side of security it has been suggested to  
remove the status return flag "same-origin" and simply keep following the  
normal rules. This would mean that if that request were to be successful  
http://x.example/y would need to include Access-Control-Allow-Origin:  
http://x.example (or a value * would also be ok if the credentials flag is  
false). I'm planning on making this change in the next few days.
