Bug description:  1 bit short of an 8 byte integer

Description:
------------
Despite having PHP_INT_MAX set to 8 bytes, It is impossible to have an int
greater than
1000000000000000000000000000000000000000000000000000000000000000.
8 Byte, or 64 bit maximum should be
1111111111111111111111111111111111111111111111111111111111111111.

In my included example, it is clear that when attempting to increase the
value above(by adding 1), simply nothing happens.

Attempting to assign a variable to a number greater than the above number
produces unpredictable results.


Reproduce code:
---------------
<?php
echo "Int Size = ".PHP_INT_SIZE." bytes.<br> ";
$status = 0x7FFFFFFFFFFFFFFF;
for($i=0;$i<=4;$i++)
{
        printf ("status = '%b'<br> ", $status);
        $status++;
}
?> 


Expected result:
----------------
Int Size = 8 bytes.
status =
'111111111111111111111111111111111111111111111111111111111111111'
status =
'1000000000000000000000000000000000000000000000000000000000000000'
status =
'1000000000000000000000000000000000000000000000000000000000000001'
status =
'1000000000000000000000000000000000000000000000000000000000000010'
status =
'1000000000000000000000000000000000000000000000000000000000000011'

Actual result:
--------------
Int Size = 8 bytes.
status =
'111111111111111111111111111111111111111111111111111111111111111'
status =
'1000000000000000000000000000000000000000000000000000000000000000'
status =
'1000000000000000000000000000000000000000000000000000000000000000'
status =
'1000000000000000000000000000000000000000000000000000000000000000'
status =
'1000000000000000000000000000000000000000000000000000000000000000'
