    [AUTOFDO] Enable ipa-split for auto-profile
    
    ipa-split is not now run for auto-profile. IMO this was an oversight.
    This patch enables it similar to PGO runs.
    
    gcc/ChangeLog:
    
            * ipa-split.cc (pass_feedback_split_functions::clone): New.
            * passes.def: Enable pass_feedback_split_functions for
            pass_ipa_auto_profile.
