Philip Chimento a74fbada42 Temporal: Don't observably iterate array in built-in calendar's fields()
Note the monkeypatch of getPossibleInstantsFor in test/built-ins/Temporal/
TimeZone/prototype/getInstantFor/argument-builtin-calendar-no-array-
iteration.js.

Other than that, all the tests are basically identical.
