Also support patterns in ``for (var p in/of ...)``
This CL extends the rewriting we used to do for ``for (let p in/of...)`` to
``for (var p in/of ...)``. For all for..in/of loop declaring variable,
we rewrite
for (var/let/const pattern in/of e) b
into
for (x' in/of e) { var/let/const pattern = e; b }
This adds a small complication for debugger: for a statement
for (var v in/of e) ...
we used to have
var v;
for (v in/of e) ...
and there was a separate breakpoint on ``var v`` line.
This breakpoint is actually useless since it is immediately followed by
a breakpoint on evaluation of ``e``, so this CL removes that breakpoint
location.
Similiraly, for let, it used to be that
for (let v in/of e) ...
became
for (x' in/of e) { let v; v = x'; ... }
``let v``generetaed a useless breakpoint (with the location at the
loop's head. This CL removes that breakpoint as well.

This allows you to put iterables into your array literals

let x = [0, ...range(1, 3)]; // [0, 1, 2]
This is done by treating the array literal up to the first

The sort method of TypedArrays sorts in numerical order by default.
This patch implements sorting based on Arrays and adds a test.
The length of %TypedArray%.prototype.sort, like Array.prototype.sort,
seems to be unspecified in ES6, so this patch lets it have the value
1, to match our interpretation for Array.prototype.sort (though 0

The idea is to make this the model for future TypedArray methods.
A possible downside could be lower array method performance
if everything gets polymorhpic (but if enough inlining happens, it
should still be fast), but on the upside, this change means that
the TypedArray methods won't create as much code size bloat.

The approach taken in this CL is to incrementally move toward the
currently-specced version of modules in ES6. The biggest change in this
patch is separating the parsing of modules from the parsing of scripts,
getting rid of the 'module' keyword and thus disallowing modules-in-scripts
as well as modules-in-modules.
The syntax supported by import/export declarations has not yet been significantly
changed, with the major exception being that import declarations require a string
as the 'from' part.
Most of the existing tests have been disabled, with a first new test added
in cctest/test-parsing.

If we hade }` the right brace was always treated as part of the
template literal. We should only treat the right brace as part of
the literal when we continue to parse the template literal after a
placeholder.

Per TC39 Nov 2014 decision.
This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

We add a new ScopeType, ScopeType.Script. The scope with
ScopeType.Script is always present in the scope chain (ScopeIterator
fakes it if neededi - i.e. if ScriptContext for a script has not been
allocated since that script has no lexical declarations).
ScriptScope reflects ScriptContextTable.

If a class extends another class and it doesn't provide a constructor,
one is created for them. We therefore need to ensure that stepping into
the constructor steps into the super class constructor.

This requires putting the original loop's body inside an inner for loop (with
the same labels as the original loop) and re-binding the temp variables in its
"next" expression. A second flag is added to the desugared code to ensure the
loop body executes at most once per loop.

Named class declarations and class expression have a const binding for
the name that is in TDZ for the extends expression.

This is currently done by generating a default constructor that looks
like this:
constructor() {
%DefaultConstructorSuperCall();
}
The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.
This is the second try. The first failed because the test was using a
array that was too large for Function.prototype.apply.
Revert "Revert "Classes: Add support for arguments in default constructor""
This reverts commit 43aa7e541df56a132608b8b4217e9da84575e4f8.

This is in preparation for making --harmony and --es-staging synonyms.
The only remaining difference currently is block-scoping, which is still
implied by --harmony, to avoid regressing on a long-available feature.
Also removes the special-casing of --harmony-proxies.

Updates Object.prototype.toString() to use algorithm described in harmony drafts.
Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.
