9559181b0e Fix worst-case behavior of MergeRemovableSimulates(). 
Currently, when a long series of removable simulates are merged, we do
this by merging them one by one as we find them.  As we merge the value
value lists of the simulates, those lists snowball so that we get a
quadratic complexity wrt runtime and memory consumption.

Instead, we gather simulates that need to be merged, and merge them
backwards starting from the last simulate.

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.

The problem was that if the # arguments specified in the function

the same, we use an arguments adapter frame to make it work. This
confuses the existing implementation to materialize the arguments

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

MakeFunctionInfo does not check for debug break points.

This fixes a regression introduced in r11866.
