7f4fa3b8f1 Call builtin code wrapped in functions from the bootstrapper. 
For the moment, we only pass the global object (the one we are setting up).
A few smaller changes were necessary to avoid failures in
test-object-observe/DontLeakContextOnObserve. Otherwise the global object
would be retained by being context allocated, leading to test failure.

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.

0d34254f8d Upgrade Symbol implementation to match current ES6 behavior. 
Refresh the implementation of Symbols to catch up with what the
specification now mandates:

* The global Symbol() function manufactures new Symbol values,
  optionally with a string description attached.

* Invoking Symbol() as a constructor will now throw.

* ToString() over Symbol values still throws, and
  Object.prototype.toString() stringifies like before.

* A Symbol value is wrapped in a Symbol object either implicitly if
  it is the receiver, or explicitly done via Object(symbolValue) or
  (new Object(symbolValue).)

* The Symbol.prototype.toString() method no longer throws on Symbol
  wrapper objects (nor Symbol values.) Ditto for Symbol.prototype.valueOf().

* Symbol.prototype.toString() stringifies as "Symbol("<description>"),
  valueOf() returns the wrapper's Symbol value.

* ToPrimitive() over Symbol wrapper objects now throws.

Overall, this provides a stricter separation between Symbol values and
wrapper objects than before, and the explicit fetching out of the
description (nee name) via the "name" property is no longer supported
(by the spec nor the implementation.)

Adjusted existing Symbol test files to fit current, adding some extra
tests for new/changed behavior.

014a86ef8c ES6: Add Object.getOwnPropertySymbols 
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-object.getownpropertysymbols

This allows you to get the symbols used as property keys for an object.

  var object = {};
  var sym = Symbol();
  object[sym] = 42;
  assert(Object.getOwnPropertySymbols(object)[0] === sym);

This is only available with --harmony-symbols

2657e432e4 ES6 symbols: implement name property 
Adds string-valued name property to symbols, and uses it for pretty-printing.

Requires allocating symbols in pointer space, with a custom iterator to skip the unboxed hash.

83d4a41dec ES6 symbols: turn symbols into a proper primitive type 
(qua last week's TC39)

Specifically:
- Install Symbol constructor function on the global object.
- Adjust code generation for typeof.
- Remove IsSymbol built-in, IS_SYMBOL macro now defined using typeof.
- Remove hack that allowed symbols as constructor results, and some other special cases.
- Remove symbol_delegate and GetDelegate function.
- Extend ToBoolean stub to handle symbols.
- Extend ToNumber to return NaN on symbols.
- Poison symbol's toString function, and thereby ToString on symbols.

090d09d685 ES6 symbols: Implement Symbol intrinsic and basic functionality 
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).
