Description:
------------
declare(strict_types=0); does not work with NULL value when using argument type declarations (see
test script).


Test script:
---------------
php7 -r 'declare(strict_types=0); function test(string $s) {var_dump($s);} test(123);'
php7 -r 'declare(strict_types=0); function test(string $s) {var_dump($s);} test(NULL);'


Expected result:
----------------
string(3) "123"
string(0) ""

Actual result:
--------------
string(3) "123"
PHP Fatal error:  Uncaught TypeError: Argument 1 passed to test() must be of the type string, null
given, called in Command line code on line 1 and defined in Command line code:1
Stack trace:
#0 Command line code(1): test(NULL)
#1 {main}
  thrown in Command line code on line 1
