Description:
------------
header('Location: foo') overrides the response code if it isn't 201 or 301-307, inclusive. With 308 Permanent Redirect now being added to HTTP 1.1, this is overly restrictive. We should prevent changing the response code for any 3xx response code.

Test script:
---------------
<?php

header('HTTP/1.1 308 Permanent Redirect');
header('Location: http://foo.bar');

?>

Expected result:
----------------
HTTP/1.1 308 Permanent Redirect
Host: localhost:8000
Connection: close
X-Powered-By: PHP/5.5.13-dev
Location: http://foo.bar
Content-type: text/html

Actual result:
--------------
HTTP/1.1 302 Found
Host: localhost:8000
Connection: close
X-Powered-By: PHP/5.5.13-dev
Location: http://foo.bar
Content-type: text/html
