Cpplint usually checks for non-const reference arguments. They are
forbidden in the style guide, and v8 does not explicitly make an
exception here.
This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

This is the first of three CLs which refactors indirect function calls
through tables with index > 0 to work without runtime calls.
The first CL introduces the WasmIndirectFunctionTable heap object. For
a table of type anyfunc within a WebAssembly instance,
WasmIndirectFunctionTable stores the size, the signature id's, the
call targets, and the reference parameters for that table. I used the
names that are already used for the matching fields of the
WasmInstanceObject.
The second CL expands the IndirectFunctionTableEntry to work also on
WasmIndirectFunctionTable objects. All changes to a function table go
through this class.
The third CL introduces uses of the WasmIndirectFunctionTable. In this
CL I change the code generation in TurboFan to replace runime calls with
direct accesses to the new WasmIndirectFunctionTable. Additionally I
extended the initialization of WasmIndirectFunctionTable, and also
implement Table.grow.

Update v8 files / build config accordingly.
- There's now a new library in third_party/inspector_protocol,
bindings/bindings.h, which is configured much like encoding/encoding.h.
It doesn't have much stuff in it yet, but will soon get more code
that would otherwise need to go into jinja templates.
It also comes with a new test, only a smoke test thus far.

To correctly fuzz the behaviour of optimized code and ICs we need to
allocate feedback vectors. So for the configurations testing these we
should turn off lazy feedback allocation.
It is also good to fuzz without lazy feedback allocation on other
configurations to flush out any other issues. So we also fuzz this with
0.35 chance. We also fuzz aggressive lazy feedback allocation (allocate
feedback vectors on first branch / return) with 0.05 chance to test
corner cases related to lazy feedback allocation.

Moreover, augment the header-generating functionality in Torque

Original change's description:
> [typedarray] Move external/data pointer to JSTypedArray.
>
> As the next step in supporting huge typed arrays in V8, this moves the
> external/data pointer from the FixedTypedArrayBase backing store to the
> JSTypedArray instance itself, and replaces the special backing stores
> with a plain ByteArray (removing all the code for the FixedTypedArrayBase

>
> Note: Several places in the code base used to check the instance type
> of the elements backing store of a JSTypedArray instead of checking the
> elements kind on the JSTypedArray map directly. Those had to be fixed,
> since the backing store is now always a ByteArray.
>
> Drive-by-fix: Move all the typed elements access related code into the
> elements.cc file to properly encapsulate the accesses.

As the next step in supporting huge typed arrays in V8, this moves the
external/data pointer from the FixedTypedArrayBase backing store to the
JSTypedArray instance itself, and replaces the special backing stores
with a plain ByteArray (removing all the code for the FixedTypedArrayBase
class hierarchy). By doing so, we can drastically simplify the system
around typed arrays.
Note: Several places in the code base used to check the instance type
of the elements backing store of a JSTypedArray instead of checking the
elements kind on the JSTypedArray map directly. Those had to be fixed,
since the backing store is now always a ByteArray.
Drive-by-fix: Move all the typed elements access related code into the
elements.cc file to properly encapsulate the accesses.

Introduce a single point to emit CodeCreateEvents for all builtins in
Isolate::Init. At this location, we cover both the case of builtin generation
(e.g. in mksnapshot) and deserialized builtins (in standard builds),
whereas previously we only emitted events post-builtin-generation.
In order to preserve behavior for bytecode handler events, pack the bytecode
and operand scale into our existing builtin metadata table.

Macros are now inaccessible from CSA except if their declaration is
marked with the "export" keyword. The implicit field accessors for class
fields are always exported.
In this CL, unwarranted access from CSA is prevented by appending a
pseudo-random suffix to non-exported names. This is to be replaced by
something more principled, namely by not including these macros at all in
the headers included from CSA.

This commit attempts to change as little behavior as possible, but it
does require reordering the fields within Map to abide by Torque rules
specifying that strong and weak fields must be in separate sections.
Also includes some Torque compiler updates:
- Allow enums (types extending from integral types) as class fields
- Rename @ifdef to @if and add @ifnot for inverse checks
- Allow void fields in class declarations, which take up no space and
emit no accessors

This patch implements the declarations of private methods, the access
of private methods would be left to a future patch.
When a private methods declaration is encountered, we now:
- Create a brand symbol during class evaluation and store it in the
context.
- Create the closures for the private methods
- Load the brand from the context and store it in the instance in the
constructor.

This CL exposes those failures.

Moves all trampoline CodeDataContainers to read-only space, making them
immutable. Containers with no 'kind specific flags' set or 'promise
rejection' flag are deduplicated by replacing them with the new canonical
CodeDataContainers roots.
This saves around 36KB from the snapshot.
