* Fix test for only {localeMatcher: "lookup"}
The expectation that "sr-Thai-RS" would be returned is only true with the
9.2.2 BestAvailableLocale ( availableLocales, locale )
https://tc39.es/ecma402/#sec-bestavailablelocale
algorithm used by 9.2.3 LookupMatcher ( availableLocales, requestedLocales )
https://tc39.es/ecma402/#sec-lookupmatcher
The default for localeMatcher is "best fit" but not "lookup" for all Intl objects.
And for 9.2.4 BestFitMatcher ( availableLocales, requestedLocales )
https://tc39.es/ecma402/#sec-bestfitmatcher
It may not match "sr-Thai-RS" for "sr" and return ["de", "zh-CN"] instead. Therefore, we need to change this test to only test on {localeMatcher: "lookup"}
* Add option to getLocaleSupportInfo
Needed to test different localeMatcher
* only test for "lookup" localeMatcher
* Get the info based on the localeMatcher
* pass in localeMatcher to getLocaleSupportInfo
These tests support the following normative change
"Normative: Allow null or undefined in Reference Records"
https://github.com/tc39/ecma262/pull/2267
The tests concerning the `delete` operator increase coverage to verify
behavior which, though related, is not altered by the normative change.
These tests are intended to guard against regressions as engines
implement the new semantics.

* Add basic tests for weekInfo
* Add basic tests for textInfo
* Add basic tests for timeZones
* Add basic tests for numberingSystems
* Add basic tests for hourCycles
* Add basic tests for collations
* Add basic tests for calendars
* Add feature for Intl.Locale-info
* add validation to branding tests for locale-info
Add additional assertion to branding tests for proposal-intl-locale-info
to make sure they don't pass spuriously when the proposal is not
implemented.
Minimize the code provided to the `assert.throws` utility in order to
reduce the possibility of false positives and to improve failure
messages in non-conforming runtimes.
These tests were designed to test the built-in "Promise.race Resolve
Element function," but ECMA262 does not describe such a function.
Contrary to the test's description, the function under test is created
by the InstantiateArrowFunctionExpression abstract operation. The
following tests verify most of the details directly (only the function
object's extensibility was not already tested by the existing tests):
- test/language/expressions/arrow-function/name.js
- test/language/expressions/arrow-function/throw-new.js
- test/language/expressions/arrow-function/prototype-rules.js
The definition of the built-in resolving functions is closely related,
but Test262 already includes tests for the corresponding concerns:
- test/built-ins/Promise/resolve-function-extensible.js
- test/built-ins/Promise/resolve-function-name.js
- test/built-ins/Promise/resolve-function-nonconstructor.js
- test/built-ins/Promise/resolve-function-prototype.js
Remove the tests and introduce one additional test to preserve coverage
while improving discoverability.
Several tests for getters and setters claim to check for an early
SyntaxError regarding mixing static and non-static propeties with the
same name. However, the tests trigger another issue: the getters have no
method body; they're missing curlies.
Fix the tests to test only the intended SyntaxError, not unrelated
SyntaxError-s.
* Change Intl.(ListFormat|DisplayNames|Segmenter)
Sync from ToObject to GetOptionsObject which throw TypeError
while the option is not object
* Add null and false to test
* Test object spread with Proxy
* Test object spread with non-enumerable keys and Proxy
* Test object rest with excluded keys and Proxy
* Test object rest with non-enumerable keys and Proxy
Add tests to make sure DateTimeFormat does not call the instanceof
operator and calls OrdinaryHasInstance instead.

1. test/built-ins/TypedArray/prototype/findIndex/BigInt/predicate-may-detach-buffer.js
It is not updated when a60a67ea88 is landed. This patch fixes it.
2. test/built-ins/TypedArray/prototype/filter/BigInt/callbackfn-detachbuffer.js
After detaching, BigInt64Array/BigUint64Array will produce undefined for indexed access. And
if `filter`'s callback says `true` for these results, we need to store `ToBigInt(undefined)`
to a newly resulted BigInt64Array/BigUint64Array and this will throw an error. But this test
assumed it does not throw. This patch fixed flag so that we do not throw that error while keeping
detached typed arrays tested.
A quite popular solution for encrypting files on Linux,
[eCryptfs](https://wiki.archlinux.org/index.php/ECryptfs), can't handle
filenames longer than 143 characters when filename encryption is enabled. It
just so happens that the name of this file was 144 characters long, which makes
pulling the repository to an encrypted folder fail.
intl402/DateTimeFormat/prototype/formatRangeToParts/date-same-returns-single-date.js is using `formatRange` and `format`.
Fix this test to use `formatRangeToParts` and `formatToParts` since it is the intention of this test.
This patch adds additional tests to intl402/DateTimeFormat/prototype/formatRangeToParts/date-same-returns-single-date.js and
intl402/DateTimeFormat/prototype/formatRange/date-same-returns-single-date.js. The new test uses two dates that are practially-equal,
and ensures the implementation uses `format` or `formatToParts` by detecting they are practically-equal.
