Compilation error for instanceof

[sergeyklay]

Steps to reproduce:

public function test07(string test) -> bool
{
    var obj;
    let obj = new \stdClass;

    return obj instanceof test;
}

The error message:

                 from /home/klay/.phpenv/versions/7.3.0-zts-debug/include/php/main/php.h:33,

This has always been a problem in php, you have to use is_a.

Fixed in the #1829
