Re: ipa-cp heuristics fixes

[Jan Hubicka]

Actually I added
      if (!ipa_is_param_used (info, i))                                         
        continue;                                                               
shortcut to gather_context_independent_values which prevents
us from recording context_independent_aggregate_values for unused
aggregate parameters. Perhaps that is causing the isssue?
We can simply record them and just avoid returning true if
all propagations happen to those.
