  Log:
    Do not lose existing constant visibility when autoloading
    
    This copies the private/deprecate constant visibility across the
    autoload.  It still is backwards compatible with setting the
    private/deprecate constant visibility in the autoloaded file.
    However, if you explicitly set public constant in the autoloaded
    file, that will be reset after the autoload.
    
    Fixes [Bug #11055]
