Description:
------------
Binding a PDO parameter with pdo_sqlite on 64bit builds with PDO::PARAM_INT 
forces the param to be cast internally to an int. This means 64bit ints will be 
cast down to 32bit ints internally even if PHP was compiled against a 64bit arch.

Test script:
---------------
$num = 100004313234244; // notice this exceeds 32 bits
$conn = new PDO('sqlite::memory:');
$conn->query('CREATE TABLE users (id INTEGER NOT NULL, num INTEGER NOT NULL, PRIMARY KEY(id))');

$stmt = $conn->prepare('insert into users (id, num) values (:id, :num)');
$stmt->bindValue(':id', 1, PDO::PARAM_INT);
$stmt->bindValue(':num', $num, PDO::PARAM_INT);
$stmt->execute();

$stmt = $conn->query('SELECT num FROM users');
$result = $stmt->fetchAll(PDO::FETCH_COLUMN);

printf("Expected: %d Received: %d\n", $num, $result[0]);

Expected result:
----------------
// expected to output
Expected: 100004313234244 Received: 100004313234244

Actual result:
--------------
// instead we get output of
Expected: 100004313234244 Received: 294714180
