      Add JSSpecialApiObjectType to fast path · f65251be
      Adithya Srinivasan authored 
      HTMLCollection and NodeList have InstanceType
JS_SPECIAL_API_OBJECT_TYPE, and therefore always run the slow case
of GetAlignedPropertyFromInternalField. This slows down the performance
of indexedPropertyGetter for both types, which are very commonly used
in websites.

      Jan Krems authored 
      Rewrites references to import.meta to a new GetImportMetaObject runtime
call. Embedders can define a callback for creating the meta object using
v8::Isolate::SetHostGetImportMetaObjectCallback. If no callback has been
provided, an empty object with null prototype is created.

This adds an example implementation to d8 that sets meta.url.

      [parser] Add use counter for U+2028 & U+2029 · d3c98121
      Mathias Bynens authored 
      The context is the following proposal to make JSON a subset of
JavaScript: https://github.com/tc39/proposal-json-superset

There’s interest in performing a side investigation to answer the
question of what would happen if we stopped treating U+2028 and U+2029
as `LineTerminator`s *entirely*. (Note that this is separate from the
proposal, which just changes how these characters are handled in
ECMAScript strings.) This is technically a breaking change, and IMHO it
would be wonderful if we could get away with it, but no one really has
any data on whether or not we could. Adding this use counter lets us get
that data.

      [api] Use query interceptor in Object.keys(). · 43bb2778
      Franziska Hinkelmann authored 
      The V8 API provides interceptors. They are not part of the
EcmaScript specification. But their behavior should be consistent.
For example, when an EnumeratorInterceptor is defined, Object.keys(),
Object.entries(), and Object.values() should all have the
same number of entries.

This CL creates consistent behavior among these
functions. If a QueryCallback is present, it is used to
filter the result from the EnumeratorCallback for
enumerable properties.

      [parsing] Add a UseCounter for labeled expression statements · 946f78a0
      Adam Klein authored 
      This was suggested by bmeurer after running into the confusing
example of:

  x => {x:x}

which might appear to be an arrow function that returns an object
literal containing its argument, but instead is an arrow function
that does nothing.

While it's unclear whether the language would change to make this
probable programmer error an actual syntax error, we can at least
gather some data on the question of whether we see any such code
in the wild.
