0a4881600d Correct property descriptors on GeneratorPrototype 
The ES6 specification does not explicitly state the attributes for the
'next' and 'throw' property descriptors, so their values are defined by
Section 17 [1]:

> Every other data property described in clauses 18 through 26 and in
> Annex B.2 has the attributes
> { [[Writable]]: true, [[Enumerable]]: false, [[Configurable]]: true }
> unless otherwise specified.

48eff34c32 [es6] don't "replace" Object.prototype.toString for --harmony-tostring 
When ObjectToString is installed on Object.prototype twice (once in v8natives.js, and once in harmony-tostring.js), this pollutes old code spaces on some devices. To prevent this, the function is only installed once, preventing test failures when the --harmony-tostring flag is flipped on by default.

af293729ad Tests that carefully checks opt/deopt status shouldn't --always-opt. 
If we optimize a function before gathering feedback it may be
peppered with soft deoptimizations. So it can't help but deoptimize.
A judicious reading of the code isn't enough to determine what the
optimization state should be in the face of such chaotic gyrations.

3b624a1796 Re-implement %Generator% intrinsic as an object 
From ES6 25.2.3 ("Properties of the GeneratorFunction Prototype
Object"):

> The GeneratorFunction prototype object is an ordinary object. It is
> not a function object and does not have an [[ECMAScriptCode]] internal
> slot or any other of the internal slots listed in Table 27 or Table
> 56.

Introduce one assertion for the value's type and additional tests for its
properties. Remove an invalid assertion that fails as a result of this
fix.

30ea626886 Remove invalid assertion 
The removed assertion consistently passes not because the invoked
`close` method internally throws a `TypeError` but because the `close`
method does not exist. The ES6 specification does not define a `close`
method on the GeneratorPrototype, so this test is a tautology.

3badfdcd50 Re-write duplicated assertions 
The modified assertions targeted the property descriptor for the
template object's first "cooked" value. The code immediately preceeding
these statements asserts these values.

Update the assertions to instead target the property descriptor for the
template object's first "raw" value (which are otherwise untested).

15ef61d468 Make sure debugger is ready for breakpoins when we process 'debugger' statement. 
On 'debugger' statement, if anything in debugger calls 'EnsureDebugInfo'
on a function, EnsureDebugInfo would compile and substitute code without
debug break slots. This causes weird behavior later when stepping fails
to work (see added test as an example).
This fix is to make sure the debugger is prepared for breakpoints in
that case as well.

Also adds extra testing for bug 468661.

49c3a60651 Do not assign positions to parser-generated desugarings. 
The root cause for the bug is that the positions assigned to desugared
code was inconsistent with the source ranges of block scopes.
Since the fact that the position is assigned causes the debugger to
break at the parser-generated statement, the fix is to remove positions
from those nodes that we do not want to break on.

The CL also teaches Hydrogen to tolerate these cases.

f6cd009efd ES6: Make function name configurable 
Function name property is now standardized in ES6. It was a Mozilla proprietary
extension before. With ES6, the property was made configurable, so that it can
be used instead of another proprietary property, displayName.

This is a revert of revert c791d84112.

Last time this broke a Chrome browser test which has since been updated:

d7e3697ddc harmony-scoping: Implement debugger support for script scope. 
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.

37bd114925 Update ObjectToString to Harmony-draft algorithm 
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.

730c3fa3e0 Don't expose Array.prototype.values as it breaks webcompat 
Some versions of Outlook Web Access test for the existence of a 'values'
property on Array instances, so adding the 'values' iterator to the prototype
(even with @@unscopeables) causes breakage.

This matches Gecko: they ship Array.prototype.{keys,entries} but not 'values'.
