description: Fast path for converting Temporal.PlainDate to Temporal.PlainDateTime by reading internal slots
info: |
sec-temporal.plaindatetime.prototype.since step 3:
3. Set _other_ to ? ToTemporalDateTime(_other_).
sec-temporal-totemporaldatetime step 2.b:
b. If _item_ has an [[InitializedTemporalDate]] internal slot, then
i. Return ? CreateTemporalDateTime(_item_.[[ISOYear]], _item_.[[ISOMonth]], _item_.[[ISODay]], 0, 0, 0, 0, 0, 0, _item_.[[Calendar]]).
