Add coverage in particular for dateStyle: undefined and timeStyle:
undefined, and for dateStyle applying to PlainMonthDay/PlainYearMonth
which were not tested.
"islamic" is underspecified because it doesn't include any information
which location and algorithms should be used to approximate new moon
observations. Instead switch to "islamic-tbla".
Adds a test for each Temporal object's toLocaleString() method, formatting
them with only one option e.g. { year: 'numeric' } and comparing it with
the corresponding output for legacy Date.
See tc39/proposal-temporal#2796.
Tweak some tests to provide coverage of new execution paths in the spec,
such as calling GetOptionsObject inside ToTemporal___; add a few new tests
for things that weren't covered before, such as rounding a PlainDateTime
at the edge of the range; and tweak the tests verifying when the
properties of the options bag are read, which I made a mistake in #4119.

Previously getISOFields() was used to get the exact value of the
[[Calendar]] and [[TimeZone]] internal slots, as well as to get the
reference ISO year for PlainMonthDay and reference ISO day for
PlainYearMonth.
Use calendarId and timeZoneId for the former and toString() for the
latter.
Without custom calendars and time zones there are actually a bunch of
things that we now can't test on implementations that don't have non-ISO
calendars or non-UTC time zones. (Alternatively, we can say that these are
functionalities that those implementations don't have to implement.)
It's no longer possible to fake built-in time zones using custom objects.
So testing DST shifts will have to use real built-in time zones. Replace
TemporalHelpers.springForwardFallBackTimeZone with America/Vancouver (it
was modelled on the DST transitions in 2000) and
TemporalHelpers.crossDateLineTimeZone with Pacific/Apia (it was modelled
on the 2011 switch to the other side of the international date line.)
These tests have to move to the intl402/ folder since non-Intl-aware
implementations are allowed (but not required) to support any built-in
time zones other than UTC.
In many cases we created a TimeZone or Calendar instance from a built-in
time zone or calendar. These tests can be trivially adapted to just use
the string ID.
Following the upstream ECMA-402 change tested in the previous commit, add
test coverage for the corresponding functionality in Temporal. Fix one
test that was erroneous.
For each Temporal type, add a test (which should not be sensitive to the
exact locale format) that ensures dateStyle affects the output, for a
Gregorian and non-Gregorian calendar.
See https://github.com/tc39/proposal-temporal/issues/2058
I wrote a similar test for Temporal.ZonedDateTime.p.toLocaleString, so
while this was fresh I decided to do the same for the other toLocaleString
calendar mismatch tests that were in staging.
Previously, "nested" time zone property bags were unwrapped up to one
level. That is, this object:
{
timeZone: {
// ...Temporal.TimeZone methods
}
}
would not be considered to implement the TimeZone protocol, but would have
its timeZone property used instead, if it were passed to an API that
required a TimeZone protocol object.
These nested property bags are no longer supported. Discussion:

This is the replacement of the old API with the new API, .timeZoneId and
.getTimeZone(). Semantics will be corrected in the following commit.

Compare semantics for custom calendars that _don't_ extend
Temporal.Calendar (and therefore don't have the internal slot) use the
value of the .id property, instead of calling toString().

I discovered these tests had omitted some arguments to the PlainDateTime
constructor, leaving the calendar in the wrong position.
The tests were technically not incorrect, since the operation
ToIntegerThrowOnInfinity on the string "gregory" gives 0. But they could
spuriously pass if the implementation didn't do argument conversion
correctly, failed to throw on eraYear being ±Infinity, but subsequently
threw RangeError anyway because the calendars of the arguments didn't
match.
For cases in the previous commit that actually removed some functionality
from tests in built-ins/, add corresponding tests in intl402/ to preserve
test coverage of that functionality for hosts that do support Intl.
Move part of the test of toLocaleString which depends on
15 Amendments to the ECMAScript® 2021 Internationalization API Specification
to intl402. Keep behavior specified in earlier chapters in built-ins
Unfortunately, in #3304 I made a last-minute mistake when I added the
uncallable value to the assertion message, and neglected to test it;
Symbols can't be converted to strings like that, so these tests would
fail. This fixes the assertion messages.

In a previous version of the specification, there was a fallback to the
intrinsic getOffsetNanosecondsFor when it was undefined.
