This refactors Map operations to update the instance descriptors and
the number of own descriptors via the SetInstanceDescriptors bottleneck.
This will allow us to add a special marking barrier for these updates.

ToBoolean and BooleanValue cannot throw exceptions so the Maybe versions
of the functions don't make sense. As such this deprecates the Maybe
versions and undeprecates ToBoolean(Isolate*). It also adds
BooleanValue(Isolate*).
Fix up all of the v8 code to not use the deprecated functions.

The "Address" type is V8's general-purpose type for manipulating memory

Don't dispatch based on the construct_stub field anymore. Rather than
read it out and jump to the construct stub, we can switch on the
builtin_id.
Builtins will always have builtin_id as a Smi, so this signals we need
to jump to JSBuiltinsConstructStub. The only exception is for uncompiled
functions, which will have kCompileLazy as the builtin_id, but need to
jump to the generic stub instead.
API function calls will have a FunctionTemplateInfo in the SFI
function_data field, and need to go to the builtins stub as well.
The final case is everything else, which should go to the generic stub.

There's three common situations in which we need to create JSFunction
objects. 1) from the compiler, 2) from tests, and 3) everything else
(mostly during bootstrapping).
This is an attempt to simplify case 3), which previously relied on
several Factory::NewFunction overloads where it was not clear how the
semantics of each overload differed.
This CL removes all but one overload, and packs arguments into a new
NewFunctionArgs helper class.
It also removes the hacks around
SFI::set_lazy_deserialization_builtin_id by explicitly passing
builtin_id into Factory::NewSharedFunctionInfo.
Drive-by-fix: Properly set is_constructor hint in
SimpleCreateSharedFunctionInfo.

Introduce a proper empty_descriptor_array, which has the proper layout
(length is 2 and the two fields are set properly). Also add a special
EnumCache class and a matching empty_enum_cache. The contract now is
that we only need to check the EnumLength on the map to know whether we
are allowed to use the enum cache. This greatly simplifies the handling
of the enum cache (and also the descriptor arrays), especially for the
future work on optimizing keyed access via the enum cache indices.

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.

Now callers of Heap::CollectGarbage* functions need to
specify the reason as an enum value instead of a string.
Subsequent CL will add stats counter for GC reason.

This way we avoid the cyclic dependency between objects.h and heap.h and still
have one definition. Add a static assert that this size is indeed smaller than
the payload of a page.
Follow ups can finally remove the dependency on spaces.h for all heap.h users.

This CL removes the IsUndefined() and Co. methods from Object and HeapObject.

- Move usable functions into proper heap-utils.h/.cc files and remove
utils-inl.h file
- Fix assumptions accross the board relying on certain behavior that is not
invariant
This is a requirement for modifying page size.

- Removing null checks as we always have the CodeRange object (it might be
invalid, but it's there)
- Account for reserved area (Win64) in SetUp so we the caller doesn't need to be
aware of it
