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.

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.

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.

ce1e10f5fc Make __proto__ a foreign callback on Object.prototype. 
This moves the __proto__ property to Object.prototype and turns it into
a callback property actually present in the descriptor array as opposed
to a hack in the properties lookup. For now it still is a "magic" data
property using foreign callbacks and not an accessor property visible to
JavaScript.

The second effect of this change is that JSON.parse() no longer treats
the __proto__ property specially, it will be defined as any other data
property. Note that object literals still have their special handling.

f15f294127 Sync laziness between BuildFunctionInfo and MakeFunctionInfo. 
BuildFunctionInfo compiles the function eagerly when there are debug
break points. However, the AST may have been parsed lazily since
MakeFunctionInfo does not check for debug break points.

This fixes a regression introduced in r11866.

0aacbf9619 Added %FlattenString and use it to speed up a regression test. 
Flattening strings is relatively costly and by doing it after every duplication
we avoid combinatorial explosion.

Note that flattening could have been done by e.g. using a regular expression,
too, but this is just another implementation detail and %FlattenString seems
general enough to be useful in other tests, too.

55e924c595 Fix CNLT regression. 
This happens when a map A with no descriptors in fast_holey_elements
mode first gets some properties, making it share descriptor arrays with
a map B to which it transitions. Then map A transitions elements kind to
dictionary_elements in map C. C stores the empty_descriptor_array in its
own transition array. When adding a property to C, C transitions to D
and shares the descriptors. If D dies, a CNLT clears the transition
array of C, making the descriptor array of A (and thus also of B) shine
through. If a property is now added to an object in state C, it'll inherit
all the properties of A (and B). If those properties had high field indices,
we do not have a large enough backing store for the single newly added
property, and we'll write out of bounds.

5d11c5ee69 Fixed Accessors::FunctionGetPrototype's proto chain traversal. 
Actually it didn't traverse that far... ;-) Did some cleanup on the way.
