    global: Lazy-define standard environment
    
    In SpiderMonkey 68, using lazy-define for the standard global properties
    will be the only option, since JS_InitStandardClasses() will go away.
    This should not change anything, only that global properties such as
    String and Number will be defined on demand instead of in advance.
