Additionally removed the `arrow-function` feature for
test/language/eval-code/direct/new.target-fn.js as it is not testing
arrow-functions, but they are mentioned in the preamble.
All other Proxy tests use the syntax `attr: function() {...}` for
defining traps, ownKeys was unique in using the shorthand syntax. Change
to longhand syntax for back-compat for partial implementations.
Thsi test for the parsing of string literals was expressed using `eval`.
This made the test more complex than necessary and also prevented the
test from providing value to ECMAScript parsers.
Remove the use of `eval` and instead express the expectation with
literal source text.
This test is technically valid because it does trigger a SyntaxError in
conforming runtimes. However, it was authored and documented to test
LegacyOctalEscapeSequence, but due to an apparent typo, it actually
demonstrates an unrelated parsing error.
Because 'legacy-octal-escape-sequence-stricts.js' sufficiently tests the
restriction on LegacyOctalEscapeSequence, remove this test rather than
correct it.
This test for string literals asserts the restriction on
LegacyOctalEscapeSequence in strict mode. It is not sufficiently
distinct from the test 'legacy-octal-escape-sequence-stricts.js' to
warrant inclusion in the test suite. Because that test includes much
more thorough documentation, it should be preferred.
A number of tests for string literals assert the restriction on
LegacyOctalEscapeSequence in strict mode code and differ only in the
escape sequence under test. Although each is valid, none of the escape
sequences are sufficiently distinct from the test
'legacy-octal-escape-sequence-stricts.js' to warrant their inclusion in
the test suite. Because that test's use of literal code makes it
consumable by parsers and because that test includes much more thorough
documentation, it should be preferred.

Test262 already includes tests to ensure the correct runtime semantics
for these forms. Add equivalent tests designed to verify that the
equivalent parsing behavior is also observed.
Verify runtime semantics through assignment to an unresolvable
reference, reducing the complexity of tests that previously relied on
the semantics of the `eval` function.
The document fragments used by the ECMAScript specification do not
conform to any particular pattern beyond the grammar defined by the URL
standard [1]. Relax the linting rule to enforce a simplified version of
that grammar.
