FWIW the changes LGTM, if we don't want these in df-core we can always 
implement the extra utility locally. It's really just a helper function 
to check if df_bb_regno_first_def_find and df_bb_regno_last_def_find 
yield the same result, meaning we only have a single definition.

Kind regards,
Andre
