This speeds up both the case from the bug (using Object.create) but also
takes care ofthe "{ __proto__: obj }" syntax, which was previously (and
erroneously) being treated the same as setting the prototype dynamically
from script using the __proto__ setter or Object.setPrototypeOf.

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.

The issue is that by handling strings with map/handler pairs instead of a special
...
version of the keyed load stub (https://code.google.com/p/v8/source/detail?r=24661 ),
I allowed polymorphism between string and non-string types in the IC. Before, the
IC would go generic.
Then, at crankshaft time, we special case when we only saw strings. The error
here is that crankshaft can't emit code that handles polymorphism between string
and non-string types. The choice is either to get that to happen (I don't deem
this necessary from a performance point of view, an IC with such type feedback
before would have gone generic), or simply check for the case of "polymorphic
with some string maps" and require crankshaft to go generic. I'll do the latter.

Implement graph trimming in ControlReducer.
...
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.
This CL is one half of the ControlReducer functionality, the other half
being branch folding.

Array.prototype.{every, filter, find, findIndex, forEach, map, some}: Use fresh primitive wrapper for calls.
...
When the receiver is a primitive value, it's cast to an Object before entering the loop. Instead, it should be cast to an Object for each function call while in the loop.

Allow identifier code points from supplementary multilingual planes.

ES5.1 section 6 ("Source Text"):
"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."
This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."
This patch is to reflect this spec change.
