--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
speculative edges come in pairs (direct, indirect edge) that is obtained by
speculative_call_info.  THen you need to sum counts (instead of taking ones
from BB) and turn them back to frequencies (because it is profile only counts
should be non-0)
