+ SNES is too slow
+ https://bugs.webkit.org/show_bug.cgi?id=29534
+
+ The problem was that the emulator used multiple classes with
+ more properties than our dictionary cutoff allowed, this resulted
+ in more or less all critical logic inside the emulator requiring
+ uncached property access.
+
+ Rather than simply bumping the dictionary cutoff, this patch
+ recognises that there are two ways to create a "dictionary"
+ structure. Either by adding a large number of properties, or
+ by removing a property. In the case of adding properties we
+ know all the existing properties will maintain their existing
+ offsets, so we could cache access to those properties, if we
+ know they won't be removed.
+
+ To make this possible, this patch adds the logic required to
+ distinguish a dictionary created by addition from one created
+ by removal. With this logic in place we can now cache access
+ to objects with large numbers of properties.
+
+ SNES performance improved by more than 6x.

+ Implement Object.defineProperty. This requires adding the API to

+
+ This is an important fix when JavaScript workers are in use, since
+ unfreed ThreadGlobalDatas leak a big amount of memory (50-100k each).
+ QThreadStorage calls the destructor of a given object, which is the
+ ThreadSpecific::Data. Unlike pthread, Qt is object oriented, and does
+ not support the calling of a static utility function when the thread
+ is about to close. In this patch we call the ThreadSpecific::destroy()
+ utility function from the destructor of ThreadSpecific::Data. Moreover,
+ since Qt resets all thread local values to 0 before the calling of the
+ appropriate destructors, we set back the pointer to its original value.
+ This is necessary because the get() method of the ThreadSpecific
+ object may be called during the exuction of the destructor.

+ check fro default mark violations in debug code. If a markChildren
+ function adds something to the mark stack, but the type info claimed

+ because we don't have a JSCell::marked function any more.
+ (JSC::MarkStack::drain): Changed a local variable from "v" to "value",

+ Heap::markCell so we can eliminate the JSCell::marked and
+ JSCell::markCellDirect functions.
+
+ * runtime/JSCell.h: Removed JSCell's markCellDirect and marked member
+ functions. Added a comment explaining that asCell should be deprecated
+ in favor of the JSValue asCell member function.
+ (JSC::MarkStack::append): Added the assertion that catches callers
+ that have set the HasDefaultMark bit incorrectly. Changed
+ code that reads and writes the mark bit to use Heap::isCellMarked and
+ Heap::markCell so we can eliminate the JSCell::marked and
+ JSCell::markCellDirect functions. Moved the overload of
+ MarkStack::append for JSValue here so it can call through to the cell
+ version. The old version had a copy of all the code instead, but that
+ repeated the conversion from JSValue to JSCell* and the check for
+ whether a value is a cell multiple times.
+ (JSC::Structure::markAggregate): Moved this function here to avoid

+
+ * runtime/JSObject.cpp:

+ How many copies of the parameters do you need?
+ https://bugs.webkit.org/show_bug.cgi?id=28701
+
+ The function parameters in JSC get copied a lot - and unnecessarily so.
+
+ Originally this happened due to duplicating FunctionBodyNodes on recompilation,
+ though the problem has been exacerbated by copying the parameters from the
+ original function body onto the executable, then back onto the real body that
+ will be generated (this happens on every function). And this is all made worse
+ since the data structures in question are a little ugly - C style arrays of C++
+ objects containing ref counts, so they need a full copy-construct (rather than
+ a simple memcpy).
+
+ This can all be greatly simplified by just punting the parameters off into
+ their own ref-counted object, and forgoing all the copying.
+
+ ~no performance change, possible slight progression.

+ Restructure Executable types so that host functions do not hold a FunctionExecutable.
+ https://bugs.webkit.org/show_bug.cgi?id=28621
+
+ All JSFunction objects have a pointer to an Executable*. This is currently always a
+ FunctionExecutable, however this has a couple of drawbacks. Host functions do not
+ store a range of information that the FunctionExecutable provides (source, name,
+ CodeBlock & information presently held on the FunctionBodyNode).
+
+ [ * nearly all... see below! ]
+
+ Instead, make JSFunctions hold a pointer to an ExecutableBase, move fields specific
+ to JS sourced executable types (source, node) into a new subclass (ScriptExecutable),
+ and create a new NativeExecutable type. We now provide a new method in JSFunction
+ to access & downcast to FunctionExecutable, but in doing so we can make an early
+ check (with an ASSERT) to ensure that the Executable read from a function will only
+ be treated as a FunctionExecutable (and thus the JS sepcific fields will only be
+ accessed) if the JSFunction is not a host function.
+
+ There is one JSFunction that currently does not have an Executable, which is the
+ object created to allow us to read out the vtable pointer. By making this change
+ we can also add a new Executable type fror this object (VPtrHackExecutable).
+ Since this means that really all JSFunctions have an Executable we no longer have
+ to null-check m_executable before us it - particularly in isHostFunction().
+
+ This patch removes CacheableEvalExecutable, since all subclasses of ExecutableBase
+ can now be ref-counted - since both JSFunction holds (and ref-counts) an ExecutableBase
+ that might be a FunctionExecutable or a NativeExecutable. This does now mean that all
+ ProgramExecutables and EvalExecutables (unnecessarily) provide an interface to be
+ ref-counted, however this seems less-bad than host functions unnecessarily providing
+ interface to access non-host specific information.
+
+ The class hierarcy has changed from this:
+
+ - ExecutableBase
+ - ProgramExecutable
+ - EvalExecutable
+ - CacheableEvalExecutable (also RefCounted by multiple-inheritance)
+ - FunctionExecutable (also RefCounted by multiple-inheritance, 'special' FunctionExecutable also used for host functions)
+
+ To this:
+
+ - RefCounted
+ - ExecutableBase
+ - NativeExecutable
+ - VPtrHackExecutable
+ - ScriptExecutable
+ - ProgramExecutable
+ - EvalExecutable
+ - FunctionExecutable
+
+ This patch speeds up sunspidey by a couple of ms (presumably due to the changes to isHostFunction()).

+ assigned when a transition was assigning a function. This had the side
+ effect of making every assignment of a function expression result in a
+ new transition, and thus a new Structure. The net result of this is that
+ the common JS idiom of
+
+ function MyObject() {
+ this.myFunction = function(...){...};
+ }
+ new MyObject();
+
+ Will produce a unique structure on every iteration, meaning that all
+ caching is defeated and there is a significant amount of structure churn.
+
+ The fix is to return the transition to its original form where it is
+ keyed off a property name + attributes tuple, but have each transition
+ support an optional transition on a specific value.

+ These only exist to allow JIT code to dereference properties off the

+ Instead just use the FunctionExecutable. Copy the m_parameters field

+ [ES5] Arguments object should inherit from Array
+ https://bugs.webkit.org/show_bug.cgi?id=28298
+
+ Make the Arguments object conform to the behaviour specified in ES5.
+ The simple portion of this is to make Arguments use Array.prototype
+ as its prototype rather than Object.prototype.
+
+ The spec then requires us to set instance.constructor to the pristine
+ Object constructor, and instance.toString and instance.toLocaleString
+ to the pristine versions from Object.prototype. To do this we now
+ make the ObjectPrototype constructor return its toString and
+ toLocaleString functions (similar to the call and apply functions
+ from FunctionPrototype).
+
+ Oddly enough this reports itself as a slight win, but given the code
+ isn't hit in the tests that claim to have improved I put this down to
+ code motion.

+ Stack overflow crash in JavaScript garbage collector mark pass

+
+ Make the GC mark phase iterative by using an explicit mark stack.
+ To do this marking any single object is performed in multiple stages
+ * The object is appended to the MarkStack, this sets the marked
+ bit for the object using the new markDirect() function, and then

+ * When the MarkStack is drain()ed the object is popped off the stack
+ and markChildren(MarkStack&) is called on the object to collect

+
+ Additionally I renamed a number of methods from 'mark' to 'markAggregate'

+ Fixed some ASSERTs in http/tests/security.
+
+ These ASSERTs were introduced by http://trac.webkit.org/changeset/45057,

+ just exposed the problem by enabling optimization in more cases.
+
+ The ASSERTs fired because we tested PropertySlot::slotBase() for validity,

+ the test could happen. Solution: Remove the ASSERT. Maybe it was valid
+ once, but it clearly goes against a pattern we've deployed of late.
+
+ The underlying problem was that WebCore would re-use a PropertySlot in
+ the case of a forwarding access, and the second use would not completely
+ overwrite the first use. Solution: Make sure to overwrite m_offset when
+ setting a value on a PropertySlot. (Other values already get implicitly

+ The dst argument provides for a crude form of copy propagation. For example,

+ load r0, 1
