The specification was changed to remove the useGrouping option in
<https://github.com/tc39/proposal-intl-relative-time/pull/81>.

The change to remove the minimumIntegerDigits option in that PR was already
taken into account; this commit also removes the reference to the issue.

This also removes some commented-out code that was left in by accident.

These are not spec tests neither identify points not already covered in the tests to cover something new from the specs

I observed each file in each of these folders and they don't contain any test matching for specific parts of ECMAScript, without a specific place for Test262.

The specification was updated in https://github.com/tc39/ecma402/pull/232.

Make doneprinthandle.js accept the input and produce the output expected by test262-harness. (#1650)

This is not a breaking change, it simply adds explicit handling to the function

Generate tests for "feature new.target"

Merge branch 'feature-new.target' of https://github.com/IgnoredAmbience/test262 into IgnoredAmbience-feature-new.target

* 'feature-new.target' of https://github.com/IgnoredAmbience/test262:
  Add feature flags for `new.target`

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.

Curation: Removed all test files that depend on $vm (implementation-contributed/javascriptcore) (#1629)

- Eliminates:
  - controlFlowProfiler/*
  - exceptionFuzz/*

Follow up to https://github.com/tc39/test262/pull/1643

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.

Proxy/deleteProperty/boolean-trap-result-boolean-true.js was missing a
feature flag for the Reflect library.
