Remove unused variables
A recent change to the specification [1] introduces parse-time errors
for certain usages of `super` within eval code. Modify all tests that
are affected by this change:
- Update the test bodies to accurately enforce the new semantics
- Rename files to better reflect the section of the specification that
they enforce
- Update test meta-data
- Change the `esid` meta-data to reflect the location of the relevant
specification text
- Remove the `es6id` meta-data as the behavior is no longer relatable
to that specification
- Introduce the `features` meta-data in cases where the test file's
new location no longer reflects all required language features

* Add tests for prototype realm inference
* Add tests for miscellaneous realm concerns
* Add tests for realm of spec-created Errors
In some cases, Error objects produced by the specification are
observable from ECMAScript code. Among these cases, some are further
differentiated in that they occur outside of any built-in function and
may be triggered through syntactic production directly. The current
realm record is commonly interpreted incorrectly under these
circumstances.
Add tests asserting that the expected realm record is used when
constructing such Error objects.
* Add tests for realm use in ArraySpeciesCreate
* Add tests for function realm retrieval
* Add tests for cross-realm behaviors of Symbols
* Add tests for GetValue and PutValue
* Add tests for realm of spec-created Arrays
In some cases, Arrays produced by CreateArrayFromList are observable
from ECMAScript code. Among these cases, two occur outside of any
built-in function and may be triggered through syntactic production
directly. The current realm record is commonly interpreted incorrectly
under these circumstances.
Add tests asserting that the expected realm record is used when
constructing arrays.

Because expectations regarding error "phase" are now expressed via test
meta-data, the test runner may now enforce this requirement on negative
tests.
Remove the "NotEarlyError" from the project source. This reduces the
amount of domain knowledge required to author tests and lessens the
potential for inconsistencies between tests.
Authored via the following command:
$ find test -type f -print0 | \
xargs -0 sed \
-i 's/^\(\s*\)negative:\s*SyntaxError\s*$/\1negative:\n\1 phase: early\n\1 type: SyntaxError/g'
The expected errors in these tests cannot be asserted with the
`assert.throws` helper function for various reasons. Re-format their
meta-data according to the latest design in order to more precisely
describe test expectations.
The file previously named `values-binding-types_.js` is not intended to
be interpreted as a test. Therefor (in accordance with the project's
`INTERPETING.md` file), its name should include `_FIXTURE` as a suffix.
* Tests for new lastIndex semantics
Add and update tests for the lastIndex semantic change introduced in
https://github.com/tc39/ecma262/pull/627.
* Address comments
This test is being added because the committee is considering changing
this evaluation order (as discussed at the May 2016 Munich meeting). The
consequences of this spec change will be more clear as a test change
than a simple test addition.
* Assert creation of 'arguments' object
Ensure that the 'arguments' object is created in cases where it is not
required by the body but is required by the parameters.
* Add tests for cases that disable "arguments" map
* Add tests for NewTarget override of bound function
* Add test for properties of exotic String objects
ECMA262 allows for an arbitrary number of "ScriptJob"s to run in a given realm.
Although there is no standard mechanism for enqueuing these jobs, many
implementations offer this functionality through custom APIs. In those hosts,
the semantics describing script interactions are directly observable.
In order to guarantee conformance to the specification in advance of a
standardized API, Test262 now requires that hosts provide a $.evalScript
function whose behavior is defined in the project's "INTERPRETING.md" file.
Use this host-provided API to ensure that implementations correctly observe the
specification text that dictates script interactions.
(In writing these tests, I noticed some gaps in coverage that are observable
from a single script execution. This patch includes a dedicated commit for
these tests that do not require $.evalScript.)
* Improve coverage of GlobalDeclarationInstantiation
* Add tests for script interactions
Use the host-provied `$.evalScript` method to assert conformance to the
specification text that defines script interactions.
* fixup! Improve coverage of GlobalDeclarationInstantiation
* Update tests for Proxy.[[SetPrototypeOf]]
Expand coverage for proxies' [[SetPrototypeOf]] and update tests to
verify that target's [[IsExtensible]] is not called anymore if trap
returns a falsy value.
Ref tc39/ecma262#331
* Add tests for abrupt completions during JSON.parse
Due to the use of the IsArray abstract operation, observing many of the
targeted semantics requires the use of a Proxy exotic object. Mark the
tests that require this unrelated ES2015 feature using a dedicated
"features" flag.
* Re-generate tests
The test generation tool has been modified in the time since these tests
were first generated and committed to the project. Re-generate the tests
using the latest version of the tool.
* Add test cases for Annex B hoisting disqualifiers
The "variable-like" function hoisting semantics defined in Annex B
extension B.3.3 is only applied if "[...] replacing the
FunctionDeclaration f with a VariableStatement that has F as a
BindingIdentifier would not produce any Early Errors [...]". Test262
previously included tests for this condition when the disqualifying
early error originated from the ScriptBody and FunctionBody productions.
Add test cases to assert the behavior when it is disqualified by all
other relevant early errors: Block statements, `for` statements,
`for-of` statements, `for-in` statements, and Switch statements.
* Generate tests
* fixup! Add test cases for Annex B hoisting disqualifiers
* fixup! Add test cases for Annex B hoisting disqualifiers
Correct test case "info" meta-data.
* fixup! Add test cases for Annex B hoisting disqualifiers
Improve test bodies
* fixup! Generate tests
