    Don't inline functions with RULES too early
    
    Trac #15445 showed that a function with an automatically
    generated specialisation RULE coudl be inlined before the
    RULE had a chance to fire.
    
    This patch attaches a NOINLINE[2] activation to the Id, to
    stop this happening.
