Avoid 2 times name iteration in Object.assign
https://bugs.webkit.org/show_bug.cgi?id=147268

Reviewed by Geoffrey Garen.

Object.assign calls Object.getOwnPropertyNames & Object.getOwnPropertySymbols to collect all the names.
But exposing the private API that collects both at the same time makes the API efficient when the given Object has so many non-indexed properties.
Since Object.assign is so generic API (some form of utility API), the form of the given Object is not expected.
So the taken object may have so many non-indexed properties.

In this patch, we introduce `ownEnumerablePropertyKeys` private function.
It is minor changed version of `[[OwnPropertyKeys]]` in the ES6 spec;
It only includes enumerable properties.

By filtering out the non-enumerable properties in the exposed private function,
we avoid calling @objectGetOwnPropertyDescriptor for each property at the same time.

many indexed properties and all the indexes have to be converted to uniqued_strings and
added to the collection of property names (though they may not be of the requested type
and will be filtered out later)

This patch introduces PropertyNameMode.
We leverage this mode in 2 places.

1. PropertyNameArray side
It is set in PropertyNameArray and it filters the incoming added identifiers based on the mode.
It ensures that PropertyNameArray doesn't become so large in the pathological case.
And it ensures that non-expected typed keys by the filter (Symbols or Strings) are never added
to the property name array collections.
However it does not solve the whole problem because the huge array still incurs the many
"indexed property to uniqued string" conversion and the large iteration before adding the keys
to the property name array.

2. getOwnPropertyNames side
So we can use the PropertyNameMode in the caller side (getOwnPropertyNames) as a **hint**.
When the large iteration may occur, the caller side can use the PropertyNameMode as a hint to
avoid the iteration.
But we cannot exclusively rely on these caller side checks because it would require that we
exhaustively add the checks to all custom implementations of getOwnPropertyNames as well.
This process requires manual inspection of many pieces of code, and is error prone. Instead,
we only apply the caller side check in a few strategic places where it is known to yield
performance benefits; and we rely on the filter in PropertyNameArray::add() to reject the wrong
types of properties for all other calls to PropertyNameArray::add().

In this patch, there's a concept in use that is not clear just from reading the code, and hence
should be documented here. When selecting the PropertyNameMode for the PropertyNameArray to be
instantiated, we apply the following logic:

1. Only JavaScriptCore code is aware of ES6 Symbols.
We can assume that pre-existing external code that interfaces JSC are only looking for string named properties. This includes:
    a. WebCore bindings
    b. Serializer bindings
    c. NPAPI bindings
    d. Objective C bindings
2. In JSC, code that compute object storage space needs to iterate both Symbol and String named properties. Hence, use PropertyNameMode::Both.
3. In JSC, ES6 APIs that work with Symbols should use PropertyNameMode::Symbols.
4. In JSC, ES6 APIs that work with String named properties should use PropertyNameMode::Strings.

[ES6] Add support for default parameters
https://bugs.webkit.org/show_bug.cgi?id=38409

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

This patch implements ES6 default parameters according to the ES6
specification. This patch builds off the components introduced with
"let" scoping and parsing function parameters in the same parser
arena as the function itself. "let" scoping allows functions with default
parameter values to place their parameters under the TDZ. Parsing function
parameters in the same parser arena allows the FunctionParameters AST node
refer to ExpressionNodes.

The most subtle part of this patch is how we allocate lexical environments
when functions have default parameter values. If a function has default
parameter values then there must be a separate lexical environment for
its parameters. Then, the function's "var" lexical environment must have
the parameter lexical environment as its parent. The BytecodeGenerator
takes great care to not allocate the "var" lexical environment before its
really needed.

The "arguments" object for a function with default parameters will never be
a mapped arugments object. It will always be a cloned arugments object.

DFG::safeToExecute() is wrong for MultiGetByOffset, doesn't consider the structures of the prototypes that get loaded from
https://bugs.webkit.org/show_bug.cgi?id=147250

Reviewed by Geoffrey Garen.

This fixes a nasty - but currently benign - bug in DFG::safeToExecute(). That function
will tell you if hoisting a node to some point is safe in the sense that the node will
not crash the VM if it executes at that point. A node may be unsafe to execute if we
cannot prove that at that point, the memory it is loading is not garbage. This is a
necessarily loose notion - for example it's OK to hoist a load if we haven't proved
that the load makes semantic sense at that point, since anyway the place where the node
did get used will still be guarded by any such semantic checks. But because we may also
hoist uses of the load, we need to make sure that it doesn't produce a garbage value.
Also, we need to ensure that the load won't trap. Hence safeToExecute() returns true
anytime we can be sure that a node will not produce a garbage result (i.e. a malformed
JSValue or object pointer) and will not trap when executed at the point in question.

The bug is that this verification isn't performed for the loads from prototypes inside
MultiGetByOffset. DFG::ByteCodeParser will guard MultiGetByOffset with CheckStructure's
on the prototypes. So, hypothetically, you might end up hoisting a MultiGetByOffset
above those structure checks, which would mean that we might load a value from a memory
location without knowing that the location is valid. It might then return the value
loaded.

This never happens in practice. Those structure checks are more hoistable that the
MultiGetByOffset, since they read a strict subset of the MultiGetByOffset's abstract
heap reads. Also, we hoist in program order. So, those CheckStructure's will always be
hoisted before the MultiGetByOffset gets hoisted.

But we should fix this anyway. DFG::safeToExecute() has a clear definition of what a
"true" return means for IR transformations, and it fails in satisfying that definition
for MultiGetByOffset.

There are various approaches we can use for making this safe. I considered two:

1) Have MultiGetByOffset refer to the prototypes it is loading from in IR, so that we
   can check if it's safe to load from them.

2) Turn off MultiGetByOffset hoisting when it will emit loads from prototypes, and the
   prototype structure isn't being watched.

I ended up using (2), because it will be the most natural solution once I finish
https://bugs.webkit.org/show_bug.cgi?id=146929. Already now, it's somewhat more natural
than (1) since that requires more extensive IR changes. Also, (2) will give us what we
want in *most* cases: we will usually watch the prototype structure, and we will
usually constant-fold loads from prototypes. Both of these usually-true things would
have to become false for MultiGetByOffset hoisting to be disabled by this change.

This change also adds my attempt at a test, though it's not really a test of this bug.
This bug is currently benign. But, the test does at least trigger the logic to run,
which is better than nothing.

In split fullscreen, we use fixed layout and scale to shrink pages down to
fit a given width. This is re-evaluated every time the document width changes.
However some pages, like recode.net, end up continually resizing because

a fixed layout size. In fixed layout, they actually use more width than the fixed

Reviewed by Dean Jackson.

Source/WebCore:

Overlap testing for compositing uses the currently laid out position of fixed
elements, without taking into account the fact that async scrolling can move
them around, and possibly under other non-composited elements. This manifested
as position:fixed elements moving over other elements on some pages when
scrolling, when they should have moved behind.

Fix by expanding the overlap map entry for position:fixed elements to create
an rect for the area they cover at all scroll locations, taking min and max
scroll offsets into account.
