Description:
------------
$interfaceReflection->isCloneable() always returns false for interfaces.

But they are, as all types are cloneable by default unless one explicitly makes __clone non public.

Additionally, it returns false even if __clone is explicitly defined:

interface Baz{ function __clone(); }
$rc = new ReflectionClass(Baz::class);
var_dump($rc->isCloneable()); // false
