description: Fast path for converting Temporal.PlainDateTime to Temporal.PlainDate by reading internal slots
info: |
    sec-temporal.plaindate.prototype.until step 3:
      3. Set _other_ to ? ToTemporalDate(_other_).
    sec-temporal-totemporaldate step 2.b:
      b. If _item_ has an [[InitializedTemporalDateTime]] internal slot, then
        i. Return ! CreateTemporalDate(_item_.[[ISOYear]], _item_.[[ISOMonth]], _item_.[[ISODay]], _item_.[[Calendar]]).
