9e757a604c Make __proto__ a real JavaScript accessor property. 
This turns the __proto__ callback from a foreign callback into a real
JavaScript accessor. It makes the accessor behavior of this property
explicit.

2816f19680 Add parser support for generators. 
This patchset begins by adding support for "yield", which is unlike other tokens
in JS. In a generator, whether strict or classic, it is a syntactic keyword.
In classic mode it is an identifier. In strict mode it is reserved.

This patch adds YIELD as a token to the scanner, and adapts the preparser and
parser appropriately. It also parses "function*", indicating that a function is
actually a generator, for both eagerly and lazily parsed functions.

Currently "yield" just compiles as "return".

a8b3215afa Change LookupForWrite to always do a full lookup and check the result. 
If we find a property in the prototype-chain that we can overwrite, and
we have a transition, keep the holder in the lookup-result as the actual
holder. We will need it for the consistency-check in GenerateStoreField.

By directly checking the entire chain we avoid having to lazily bail out
to a copy of the miss stub while generating the Field Store IC.

Currently this CL disallows a normal non-receiver holder, given that
that would require a positive lookup + details verification to ensure
the property did not become read-only. This fixes the regressions in the
attached tests.

b347a0dcae Correctly materialize arguments object in Runtime_DebugEvaluate. 
The problem was that if the # arguments specified in the function
declaration and the # arguments passed to the function are not
the same, we use an arguments adapter frame to make it work. This
confuses the existing implementation to materialize the arguments
object.

9bebd23d5c Fix %GetArrayKeys to not skip non-enumerable indices 
This is one step in the direction of fixing a range of small bugs in the array methods when dealing with non-standard element attributes.

Added tests exercising this behavior for shift and unshift.

For Proxies and Interceptors, the behavior of %GetArrayKeys is now to just return an interval, rather than trying to list all their indexed properties. In the Proxy case, this seems like the only way to avoid an observable difference between smart and non-smart array methods. For Interceptors, the usual case (in WebKit, anyway) is for them to have all indices in [0, length), so enumerating them won't be any better than simply iterating over that range.

- 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.

002ba9c76d Turn Flags into a uint32_t typedef. 
We cannot rely on C++ compilers inferring the int-type from the enum
value range. Whereas Linux/OSX find uint32_t as type for [0,MaxUInt32],
Windows insists it's int.

Update the test to execute its original intent on all platforms: 1 value
larger than max arguments, 1 smaller than max arguments (on all
platforms). This makes the test run a lot faster.
