A list of DIE values.

This is a singly-linked list, but instead of reversing the order of insertion, we keep a pointer to the back of the list so we can push in order.

There are two main reasons to choose a linked list over a customized vector-like data structure.

  1. For teardown efficiency, we want DIEs to be BumpPtrAllocated. Using a linked list here makes this way easier to accomplish.
  2. Carrying an extra pointer per DIEValue isn't expensive. 45% of DIEs have 2 or fewer values, and 90% have 5 or fewer. A vector would be over-allocated by 50% on average anyway, the same cost as the linked-list node.
