    Occurrrence analysis improvements for NOINLINE functions
    
    This patch fixes #14567.  The idea is simple: if a function
    is marked NOINLINE then it makes a great candidate for a loop
    breaker.
    
    Implementation is easy too, but it needs a little extra plubming,
    notably the occ_unf_act field in OccEnv
