    Annotate empty bb with all debug_stmt with location of phi in the
single_succ.

    For an empty BB with all debug_stmt, it will be ignored by
    afdo_set_bb_count, but it can be set with count of single successors
    PHIs which edge from the BB.

    gcc/ChangeLog:

            PR gcov-profile/118581
            * auto-profile.cc (autofdo_source_profile::get_count_info):
            Overload the function with parameter gimple location instead
            of stmt.
            (afdo_set_bb_count): For !has_annotated BB, Check single
            successors PHIs corresponding to the block and use those
            count.
