  -----------
  [GVN] use `AssertingVH` for leaders to improve compilation time (#175870)

Replace the manual check in `verifyRemoved()` with `AssertingVH`
instrumentation. For cases where the leader table becomes very large,
this is a cheaper way to verify we don't have dangling entries in the
leader table.

For this change, we must implement a move constructor for `AssertingVH`
so that we can keep the first entry as an inline-allocated node that
will be handled correctly as the table grows.
