static LongMinHeap newArrayHeap(int elements, IntBinaryOperator tieBreaker) {
    return new ArrayLongMinHeap(elements, tieBreaker);
  }
Returns a new min-heap where each element has 4 children backed by elements in an array.
<p>
This is slightly faster than a traditional binary min heap due to a shallower, more cache-friendly memory layout.
