When the multiplication steps fail, they have already thrown an

Without --harmony-function-tostring, anything other than a JSFunction

them. But with the toString revision, anything callable allows toString
(and for non-Functions returns the good old "function () { [native code] }"

Private fields should not return undefined on access miss, but instead
should throw a TypeError.
This patch uses a bit on v8::Symbol to mark if this symbol is a
private field or not.
This patch also changes the LookupIterator code path that deals with
LookupIterator::State::DATA to deal with JSReceiver instead of
JSObject.
Note: the error message doesn't output the field name, but that's a
WIP.

Report an error during scope analysis if we're unable to find a

to access a private field that was not defined or if we're outside
the class scope.
This doesn't correctly throw an early error when pre parsing a top

A version of the spec change from
https://github.com/tc39/ecma262/pull/988, but applied to the
Async-from-Sync iterator type.
This change does not modify generated bytecode (but maybe it should to
take advantage of load IC feedback for loading "next"). Doing this grows
bytecode by quite a bit, since it's necessary to throw-if-not-an-object
before loading "next" (which currently gets to live in a code stub
instead).
