    [heap] Reland "Make non-atomic markbit operations consistent with atomic ones." · db13d801
    ulan authored
    Now non-atomic color transition operations return a boolean indicating
    whether the transition succeeded or not.
    
    This allows to replace color check and transition operations with a
    single transition operation. For example:
    
    if (IsWhite(object)) {
      WhiteToBlack(object);
      Foo();
    }
    
    becomes
    
    if (WhiteToBlack(object)) {
      Foo();
    }
