Description:
------------
When PHP is used as a FastCGI it outputs incorrect Status: headers.

For example, a redirect triggered by header("Location: http://x.com/")
returns "Status: 302", not "Status: 302 Moved Temporarily" as is explicitly required by the FastCGI specification.

This leads to most web servers returning "HTTP/1.1 302" instead of "HTTP/1.1 302 Moved Temporarily", thereby breaking some very picky browsers.

This problem also also occurs with 404 if a PHP file could not be found, and I'm sure every other type of "Special" response. This makes it different than bug 41738.

Reproduce code:
---------------
--- Test 1
<?php
        header("HTTP/1.1 302 Moved Permanently");
        header("Location: http://www.google.com/");
?>

$ php-fcgi fun.php
Status: 302
Location: http://www.google.com/
Content-type: text/html

--- Test 2
<?php
        header("Location: http://www.google.com/");
?>
$ php-fcgi fun.php
Status: 302
Location: http://www.google.com/
Content-type: text/html

--- Test 3
<?php
        header("Status: 302 Moved Temporarily");
        header("Location: http://www.google.com/");
?>

$ php-fcgi fun.php
Status: 302
Status: 302 Moved Temporarily
Location: http://www.google.com/
Content-type: text/html

Note the duplicate "Status:" headers, which is dissallowed by the FastCGI spec.
