This makes v8's _monkeyYaml happy --- without it, the info block never ends, and we fail to parse the `features` key.
An explicit indentation marker isn't used because monkeyYaml doesn't supported it, and adding it might slightly slow things down.
Using PyYAML instead was considered, but after trying it, I don't think it looks viable. [simple test cases](https://gist.github.com/caitp/4a59a67f671907c11051a1b7bd5fdaae)
- Changes associated with spec changes (tc39/proposal-string-matchall#41)
- Update spec comments
- Added test verifying error thrown when `regexp[Symbol.matchAll]` is not callable
- Added test verifying `ToString` is called on `receiver`
- `Proxy/getOwnPropertyDescriptor/call-parameters.js`
Fixes a call to `Object.getOwnPropertyDescriptor` without the prop
param. Not actually a huge problem, as the test wasn't depending on
it.
- `Proxy/getOwnPropertyDescriptor/result-type-is-not-object-nor-undefined`
This test asserted that `function() {}` should throw with the
following spec step, which is incorrect, as functions are typed as
`Object` in the spec.
"""
1. If Type(trapResultObj) is neither Object nor Undefined, throw a
TypeError exception.

Migrating all tests to this API is necessary to prevent tests from hanging indefinitely when a SAB is sent to a worker but the code in the worker attempts to create a non-sharable TypedArray (something that is not Int32Array or BigInt64Array). When that scenario occurs, an exception is thrown and the agent worker can no longer communicate with any other threads that control the SAB. If the main thread happens to be spinning in the $262.agent.waitUntil() while loop, it will never meet its termination condition and the test will hang indefinitely.
Because we've defined $262.agent.broadcast(SAB) in https://github.com/tc39/test262/blob/master/INTERPRETING.md, there are host implementations that assume compatibility, which must be maintained.

Increase coverage for the Intl.DateTimeFormat constructor by adding a
test that confirms that ToObject(...) is appropriately called inside the
implementation.
Four tests were documented as asserting the interpretation of line
terminators within multi-line comments, but the source code did not
actually demonstrate this condition.
Introduce new tests that demonstrate the intended functionality and
place them in the correct directory.
Previously, these tests simply compared against an equivalent regular expression pattern by generating a large string containing either all code points up to U+FFFF or U+10FFFF, depending on the `u` flag, and then performing:
str.replace(re, '') === str.replace(otherRe, '');
These two `String#replace` calls can be optimized into a single `RegExp#test` call by following the pattern used in the property escapes tests at https://github.com/mathiasbynens/unicode-property-escapes-tests.

* AsyncFunction: Add tests ensuring the new 1-tick await behaviour
This commit adds 3 tests ensuring the optimized behaviour of await
(see https://github.com/tc39/ecma262/pull/1250) in the following cases:
- async functions
- yielding from async generator functions
- for-await-of loops
* AsyncFunction: Add tests ensuring the monkey-patched promises behaviour
This commit adds 2 more tests ensuring the optimized behaviour of await
(see tc39/ecma262#1250) in the following cases:
- awaiting on a native promise with monkey-patched "then"
- awaiting on a non-native promise (a "thenable" object)
* AsyncFunction: Add tests ensuring the non-native promises behaviour
This commit adds 1 more tests ensuring the optimized behaviour of await
(see tc39/ecma262#1250) in the following cases:
- awaiting on a non-promise, non-thenable object
It also renames the previous test for non-promise (a "thenable" object)
to distinguish from the new case.
The commit adds checks for proper await/promises interleaving in the
aforementioned cases and includes a small code clean-up.
* AsyncFunction: Refactor tests ensuring the new 1-tick await behaviour

The tests for the parsing of compound assignment expressions were
expressed using eval. This made the tests more complex than necessary
and also prevented the tests from providing value to ECMAScript parsers.
Remove the use of eval and instead express the expectations with
literal source text.
