Bug description:Integer overflow does not cast as float

Description:
------------
The manual (http://php.net/manual/pl/language.types.integer.php) includes
the following segment to cover integer overflow:

<?php
$large_number =  2147483647;
var_dump($large_number);
// output: int(2147483647)

$large_number =  2147483648;
var_dump($large_number);
// output: float(2147483648)
?>

However when I try this on my recently upgraded server they are both output
as int(2147483647)

Test script:
---------------
$large_number =  2147483647;
var_dump($large_number);

$large_number =  2147483648;
var_dump($large_number);


Expected result:
----------------
I expect to see;

int(2147483647)
float(2147483648)

As I do on my box running 5.3.1


Actual result:
--------------
int(2147483647)
int(2147483647)
