Instead of a hard-coded list of function addresses, we now use a flag
on the AccessorInfo object to annotate whether the getter can cause any
side effect.
Future changes will extend this to InterceptorInfo, CallHandlerInfo, and
expose this through the API.

This fixes debug-evaluate in the presence of a de-materialized function
object. The creation of an arguments object is now requested based on a
given frame (potentially inlined) instead of a target function. It makes
sure that multiple calls to {StandardFrame::Summarize} don't cause any
confusion when they give back non-identical function objects.

Rename |property_attributes| to |initial_property_attributes| and ensure
that it is used as a storage of values only for AccessorInfos installed in
API Templates (i.e. ObjectTemplate and FunctionTemplate).
When an AccessorInfo is installed directly into an existing JS object
(via JSObject::SetAccessor) or into a DescriptorArray (when certain V8
objects' shapes are configured) it is not necessary to thread attributes
being set through the AccessorInfo instance.

Native setters (see AccessorInfo in accessors.h) didn't have the ability
to return a result value. As a consequence of this, for instance, Reflect.set
on the length property of arrays had the wrong behavior:
var y = [];
Object.defineProperty(y, 0, {value: 42, configurable: false})
Reflect.set(y, 'length', 0)
The Reflect.set call used to return true. Now it returns false as
required by the spec.

In ES2015, the "byteLength" and "byteOffset" properties of DataViews are
getters on the prototype, so the previously-used strategy of special-casing
them using only the receiver map is invalid.
A future CL will need to use the same strategy which will be taken for
TypedArray "length", "byteLength", and "byteOffset": adding a prototype
chain check.

There are a bunch of places in our builtins where we use %_Arguments and
%_ArgumentsLength for no good reason, as arguments object and/or rest
parameter is as good and performant in these cases. Now the only uses
of %_Arguments and %_ArgumentsLength left are in string.js, which
requires dedicated investigation.

This is the first step of turning the v8.h file into a normal header
instead of an include-the-world header. The new rule is that no other
header files are allowed to include v8.h, which is enforced by DEPS.
Also the number of includes inside the v8.h file has been drastically
reduced. Basically the last missing piece is the inclusion of the big
objects-inl.h file.
This in turn makes many headers follow the IWYU principle.
