Philip Chimento 96e31e7e28 Temporal: Tests for round() and since()/until() using the same code path
This should produce all the same results (except for a change to weeks
balancing in round(), which is now more consistent with since()/until())
but leads to different observable user code calls.

Philip Chimento b4b574fca1 Temporal: argument-propertybag-calendar-year-zero testing the wrong thing
These tests were supposed to test an invalid ISO string being used as the
`calendar` property in a property bag. Instead they were testing being
used as an invalid ISO string directly where a PlainDate input was needed.
(That is also already covered elsewhere.)

Philip Chimento d7aec8e178 Temporal: Add test for Duration going out of range after rounding

Philip Chimento 984f3cc284 Temporal: Tests for correct intermediate value in ZonedDateTime difference/rounding
These test cases ensure that DST disambiguation does not take place on
intermediate values that are not the start or the end of the calculation.

Note that NormalizedTimeDurationToDays is no longer called inside
Temporal.Duration.prototype.add/subtract, so a few tests can be deleted.

Other tests need to be adjusted because NormalizedTimeDurationToDays is
no longer called inside Temporal.ZonedDateTime.prototype.since/until via
DifferenceZonedDateTime, although it is still called as part of rounding.

In addition, new tests for the now-fixed edge case are added, and for the
day corrections that can happen to intermediates.

Philip Chimento 49e56acc67 Temporal: Tests for date difference algorithm
This adds tests specifically for every kind of case that changes due to
the tweak to the date difference algorithm: differences from a longer
month to a shorter month, when the months are adjacent, in the same year
but not adjacent, and in different years.

Also adds tests for a case that does *not* change, but would trip on an
incorrectly implemented algorithm: when the intermediate months value
falls at the end of February.

There was incidental coverage of the change to the date difference
algorithm in other tests. Those are adjusted, as well.

Normative change: https://github.com/tc39/proposal-temporal/pull/2759

Adapts the tests that checked arbitrarily long loops, to now check that an
exception is thrown if the loop would happen.

Adds tests that exercise the newly added checks on return values of
getPossibleInstantsFor and getOffsetNanosecondsFor that limit UTC offset
shifts to 24 hours or less.

Also updates some step numbers in related tests.

André Bargull 0de91996e7 Add tests for precise results in Duration.p.total and ZonedDateTime.p.hoursInDay
The existing tests didn't cover some edge cases where implementations

least one of `numerator` and `denominator` can't be exactly represented
by an IEEE-754 double precision floating point value.

"precision-exact-mathematical-values-5.js" gets added in #3961, so the
new tests from this commit start at "precision-exact-mathematical-values-6.js".

Philip Chimento 01ec9938bb Temporal: Limit day length calculations to safe integers
NormalizedTimeDurationToDays can no longer loop indefinitely, because at
a certain point we will hit the upper bound of MAX_SAFE_INTEGER, so rename
the test to reflect that it can loop an arbitrary but limited number of
times.

Add a test for the RangeError condition in NormalizedTimeDurationToDays
when the time zone calculates a day length that is not a safe integer
number of nanoseconds.

While editing these tests, rename them to match the current name of the AO
and make sure the step numbers are up to date. (Normally I wouldn't care
so much about that, but these tests can be pretty confusing so it's good
to be able to refer to the spec text.)

largestUnit in duration rounding has changed since that test was written.

Philip Chimento 8bc3dbb234 Temporal: Move non-ISO calendar tests to intl402/
We'll do this for now, then separately work on migrating all of the tests
that require a non-ISO8601 calendar but aren't dependent on it being any
particular calendar.

This adds coverage for each possible outcome of compare(), where each unit
is greater, lesser, or equal.

Philip Chimento 1f0fc4e0ad Temporal: Tests for PlainDateTime exposed in DisambiguatePossibleInstants
In the AO DisambiguatePossibleInstants, a PlainDateTime instance is passed
to user code. This instance should have the built-in ISO 8601 calendar.
Here are some tests that ensure it does.

See tc39/proposal-temporal#2671.

Philip Chimento 70c36b6584 Temporal: Tests for dates out-of-range when finding end of month
In PlainYearMonth arithmetic, we need to find the end of the month when
adding a negative duration or subtracting a positive one. This end of the
month can be out of range.

Test case based on one provided by Anba. See issue:

André Bargull f0c16faee2 Fix symbol-tag-generators-builtin.js
Two issues:
1. There was a typo, the first `gen` should have been `genFn`.
2. And the last `toString` result should be `'[object Generator]'`,
   because `Object.getPrototypeOf(gen) == genFn.prototype`. And the
   `@@toStringTag` property of `genFn.prototype` is inherited from
   `Generator.prototype[@@toStringTag]`.

That also means the "iterator-helpers" flag isn't needed for this test.
