a66fddb397 Fix MSVC error in PointerWithPayload::SetPayload().
In a DCHECK inside SetPayload(), MSVC gives a C4806 warning. Use the
right types to avoid this.

Also add pointer-with-payload.h to BUILD.gn.

76968a2ff3 [ubsan] Introduce ObjectPtr and port PropertyArray
This CL gives a first look at the new way to represent tagged object
pointers in C++.
It adds infrastructure in Handles and the garbage collector to deal
with the new object type, and ports a first class to the new world.

  from JSArray with the application of more rigorous typing.
- add micro benchmarks for testing all the interesting slice cases

Also update a few assorted places in .tq code to make them more
idiomatic.

The original version of this patch had an overly agressive assert that has
been loosened.

bac7dad666 [Build] Disable build-time untrusted code mitigations on non-Android platforms and ia32.
Non-Android platforms are protected in Chrome by site isolation, therefore we can
disable the untrusted code mitigations. We still enable them on Android, and on
simulator builds since that is where we do much of the correctness testing for Android.

Mitigations for ia32 are disabled since they conflict with upcoming work on an ia32
root register.

952c097679 [builtins] Port Array.p.join to Torque.
This also includes ports of Array.p.toString and Array.p.toLocaleString.
Many parts of the old JS implementation are preserved, because
TypedArray.p.join still relies on it.  These will be removed once
TypedArray.p.join is ported to Torque.

To simplify implementation, special handling of extremely sparse arrays
has been removed.

Performance improvements vary by array size, elements, and sparse-ness.
Some quick numbers and graphs are here:

f602712f6f [snapshot] Create a ReadOnly snapshot
In preparation for sharing RO_SPACE between all Isolates within a
process, this first pulls RO_SPACE out of the Startup snapshot and puts
it in its own ReadOnly snapshot.

The snapshot is first populated with the read-only roots. After that the
StartupSerializer serializes as before but starting from the first
mutable root. References to objects in the ReadOnly snapshot that aren't
themselves roots are added to a new cache called ReadOnlyObjectCache
which functions like the PartialSnapshotCache but lives in the
ReadOnlySerializer rather than the StartupSerializer. These cache
entries are referenced using a new bytecode: ReadOnlyObjectCache. (To
make room for this, the ApiReference bytecode has been moved).

To reduce code duplication, the StartupSerializer has been refactored to
create a new base class RootSerializer, which ReadOnlySerializer also
subclasses. The base class is responsible primarily for keeping track of
already serialized roots and visiting the roots.

7c2aef087e [d8] Add --stress-delay-tasks flag
This flag stresses different interleavings of background and foreground
tasks by delaying the execution of each task by a random value between
0 and 100ms (with a quadratic distribution favoring smaller delayes).

The implementation is encapsulated in the new {DelayedTasksPlatform}
class, which wraps each task in a {DelayedTask} which first sleeps for
the given number of microseconds, then executes the actual task.

Both the old {PredictablePlatform} and the new {DelayedTasksPlatform}
are moved to the new d8-platforms.cc file with an interface to create
them in d8-platforms.h.

This change reduces the "serialize standard objects" on TypeScript

daa296b564 [interpreter] Always put bytecode handlers in builtins table
This always creates the bytecode handlers as part of the builtins table
regardless of the V8_EMBEDDED_BYTECODE_HANDLERS definition.

Lazy deserialization of bytecode handlers is enabled for this flow by
moving the three lazy bytecode deserializers from the strong roots into
the builtins table (ensuring that they not marked lazy themselves).

To simplify lazy deserialization, the illegal bytecode handler is made
non-lazy so that GetAndMaybeDeserializeBytecodeHandler doesn't to know
about it.

Since the bytecode handlers are now always part of the builtins table,
many bytecode specific methods are removed, including logging and in
BuiltinsSerializer and BuiltinsDeserializer.

Removes setup-interpreter.h, setup-interpreter-internal.cc and
builtin-snapshot-utils.*.
