description: Fast path for converting Temporal.ZonedDateTime to Temporal.Instant
info: |
    sec-temporal.instant.compare steps 1–2:
      1. Set _one_ to ? ToTemporalInstant(_one_).
      2. Set _two_ to ? ToTemporalInstant(_two_).
    sec-temporal-totemporalinstant step 1.b:
      b. If _item_ has an [[InitializedTemporalZonedDateTime]] internal slot, then
        i. Return ! CreateTemporalInstant(_item_.[[Nanoseconds]]).
