Debug counter patch

First bad debug counter value is -fdbg-cnt=ipa_mod_ref:2793.
Difference is for: TriaObjectAccessor<3, 3>::operator++():

  LTO stores:
    Limits: 32 bases, 16 refs
      Base 0:struct TriaObjectAccessor (alias set 172)
        Ref 0:int (alias set 6)
          access: Parm 0
          access: Parm 0 param offset:0 offset:0 size:32 max_size:32

  while (this->present_index
         >=
        
static_cast<int>(this->tria->levels[this->present_level]->hexes.hexes.size()))
    {
                                       // no -> go one level up
      ++this->present_level;
      this->present_index = 0;
                                       // highest level reached?
      if (this->present_level >= static_cast<int>(this->tria->levels.size()))
        {
                                           // return with past the end pointer
          this->present_level = this->present_index = -1;
          return;
        };
    };
}

hope it helps.
