      [utils] Improve BitVector performance · 11de0762
      Clemens Backes authored
      Avoid most of the {is_inline()} checks by having a {data_begin_} pointer
      which either points at the inline storage or at the zone-allocated
      memory.
      This replaces a dynamic branch by a memory indirection, which is
      beneficial for big (non-inline) BitVectors. For small BitVectors we will
      have to see what the bots say; the hypothesis is that a memory load is
      still faster than a dynamic branch.
      
      Apart from better performance, this change allows for simpler code in
      many places, including the iterator implementation.
