Reproduce Make Debug=1

POC:

assert = function () {};

assert.sameValue = () => {};

assert.notSameValue = () => {};

assert.throws = () => {};

try {
  var f = new Function(null);
} catch (e) {
  throw new Test262Error('#1: test fails with error ' + e);
}

assert.sameValue(f.constructor, Function, 'The value of f.constructor is expected to equal the value of Function');
assert.sameValue(f(), undefined, 'f() returns undefined');

reportCompare(0, 0);
