Philip Chimento 41ffc678b0 Store strings or objects in Temporal objects' [[Calendar]] slot
In several tests involving custom calendars, we need to change the
implementation of dateFromFields/monthDayFromFields/yearMonthFromFields so
that the returned object gets the receiver as its calendar after chaining
up to the builtin implementation.
